Ways of Extracting Gold From Printed Circuit Boards

There are various methods to remove these minute traces of gold from printed circuit boards, processors, and other peripherals. First requirement is milling of the PCB to expose the gold in the chips. Various methods can be used to break or mill the printed circuit board. The easiest and cheapest way of extracting gold from Printed Circuit Boards would be to mechanically cut off the tops of the microchips and carry out forging to melt all the metal that is present inside the chip. Gold has a higher molecular weight which makes it denser and heavier than other metals. Hence, any of the traditional methods of separation such as skimming, draining lighter metals or settling tank for heavier metals can be used.

There's another method for extracting gold from printed circuit boards in which, the Printed circuit board scrap is treated with one part concentrated nitric acid and two parts water at 70-80°C for 1 hour, which dissolves the base metals. As a result, it liberates the chips from the PCB.

Note: We will refer printed circuit boards as PCB in short hereafter.

Ways of Extracting Gold From Printed Circuit Boards

Coming back to the process, after solid and liquid components are separated, the chips along with some metallic residue and Ti02 precipitate are mechanically crushed. This liberates the base and gold metal present within the protective plastic or ceramic chip.

The base metals in this pulverized product are further dissolved by leaching with the same composition of nitric acid and water. The remaining solid residues, crushed chips and resin and solid particles of gold are treated with aqua regia by leaching process at varying and suitable times and temperatures. Gold is then precipitated from the leaching product with ferrous sulphate.

There are plethora of options to extract gold from processors, PCBs, and other similar things. For extracting gold from printed circuit boards even in minute quantities, you may require a large number of PCBs. A metric ton would approximately have 80 to 1600 grams of gold. With evolving technology and development in PCB design, the amount of gold used for fabrication and creation of components is reduced. Moreover, before extraction you need to figure out the potential earnings involved with the amount of gold available on these PCBs, so that the cost of retrieving the gold does not exceed the cost of the gold obtained.

More so, there are many more things to be considered, before you try anything of this sort, and try to gain handsome profits out of all your hard work. Hence, before extracting Gold from Printed Circuit Boards, you need to do an economic assessment on the value of the recoverable gold to make the process worthwhile.

Various chemicals have the ability to remove and refine gold such as sodium cyanide and sodium meta nitro benzene sulphonate. Sodium cyanide is the cheapest available unless you can find calcium cyanide. However, the overall methodology is fairly complex in comparison to the other conventional ways. There are other ways of even using chemicals for Extracting Gold from Printed Circuit Boards.

The most important thing is to make sure your record is clean, If there is 1 suspicious mark on your record then don't bother applying.

CIA Salary - The Average CIA Salary is Between 30k and 60k

The best advice I can give is to run a background record check on yourself by using a service that also uses the CIS database (same as the CIA uses) such as the official Background Record Check website. By doing this you can make sure your record is clean and that there is no false information (which is common) on your background record.

The source of most of this information is a guide I found at CIA employment which goes into detail on the exact steps you need to take in order to join the CIA.

Good Luck,

Forensic Blood Spatter Analysis - Stains And Spatter From Blood

About six quarts of blood is pumped throughout the entire vasculature in the body of an adult. When that circulation is interrupted by trauma-from bullets, a blunt object, or a knife-some of that blood is spilled. In the event of a violent confrontation or a shooting, that blood is usually spurted forth in scattered drops, or spattered.

The suggestion of a blood-spattered, blood-stained crime scene is horrible. The positions of the blood stains or the patterns of the blood spatter tell a meaningful story to a crime scene investigator. Such evidence can be damning for the defendant in court.

Computer Forensics

From the number and the location of the stains, it is possible to ascertain the movements of the victim with respect to his attacker. From blood spatter analysis, it is also possible to determine the direction from which the attack came. The proximity of the bloodstain to the victim can indicate the kind of impact the victim received, the kind of object that created his wounds, the number of strokes that were inflicted, and the location of the victim and the offender during and after the crime was perpetrated.

Forensic Blood Spatter Analysis - Stains And Spatter From Blood

Such evidence can be corroborated by statements taken from suspects or witnesses. There have been many occasions in which a perpetrator asserts that the victim's death was accidental, but blood spatter analysis contradicts his claim. Whenever blood drips, it produces stains that are circular in shape. However, when blood is thrown forcefully, as from a blow to the head, it creates stains that are elongated, if not ovoid, in shape. The longer the shape of the blood stain, the harder the blow the victim received.

Crime scene investigators take pictures of blood stain and blood spatter evidence and carefully analyze the patterns. In the past, forensic scientists have tried to study blood spatter evidence by what is known as directional analysis. Directional analysis involves using strings attached to certain points in the spatter pattern and tracking these back to a more likely source of the blood. Nowadays, a computer software program called BackTrack enables investigators to analyze spatter patterns digitally and graphically by using computer generated strings. The software user enters into the computer data that includes the width, length, direction, and location of each blood drop. Then the computer calculates an angle of attack for each drop and comes up with a flight trajectory backward from each. Where more than one of the trajectories meet, the criminal investigator can determine the position of the original injury.

Given enough time, an offender may try to remove blood stains and spatter by washing towels, blankets, and clothing, or by wiping down furniture, floors, and other surfaces. Luminol, a chemical reagent that reacts with the protein hemoglobin found in blood, can reveal even the minutest traces of blood. This chemical causes blood to fluoresce, or glow, with a bright green color.

Computer Forensics Examiners

Computer forensics examiners are professionals who use analytical and investigative techniques to provide digital evidence for a specific or general activity.

The International Society of Forensic Computer Examiners provides the Certified Computer Examiner (CCE) certification for individuals who are interested in making a career in the field of Computer forensics.

Computer Forensics

The CCE certification is provided with an intention to professionalize and further the field and science of computer forensics. The CCE certification provides a fair, uncompromised process for certifying the capability of forensic computer examiners. This certification is universally recognized, which helps in setting high and ethical forensic standards for forensic computer examiners.

Computer Forensics Examiners

CCE certification is only given to individuals with no criminal record. Examiners are certified only after they pass online exams and successfully perform actual forensic examinations on three test medias. The certified examiner must adhere to the ISFCE code of ethical standards and professional responsibilities.

Before trying for certification, it is recommended that one has a proper understanding of basic rules of evidence, as they are related to the seizure or acquisition of magnetic media, handling, marking and storage of electronic evidence, the ?chain of custody? and the ?right to privacy.?

Computer examiners are trained in proper evidence handling and documentation. With a logical thought process and investigative instincts, these individuals are able to operate at a totally professional level.

People with a military background, government or former law enforcement officers have a chance to be successful computer forensic examiners, as they already have developed a fine investigative instinct.

Certified Computer forensic examiners are held in high regard. This is because an increasing number of companies and government agencies need them.

CCE certification is becoming a valuable credential for computer forensic examiners. Unfortunately a number of computer forensic examiners have false certification, so it is advisable to beware of examiners whose credibility can always be challenged.

Definition of Forensic Science

Forensics is a field of science dedicated to the methodical gathering and analysis of evidence to establish facts that can be presented in a legal proceeding. Though crime scenes and laboratories are perhaps, most often associated with forensics, there is also computer or network forensics, forensic accounting, forensic engineering and forensic psychiatry, among other specialized fields that are today an integral part of forensics. In the United States of America, forensics was a fairly obscure topic for the general public until the double-murder trial of Orenthal James Simpson in 1995. In the historic case that gripped the entire nation, weeks of testimony were heard on DNA blood evidence, shoeprint evidence, fiber evidence and other forensics. Since then, a bevy of forensics-based television shows have regularly topped the ratings, making it a household word.

Those who collect forensic evidence must follow strict procedures to protect the evidence from getting contaminated or destroyed, and must preserve the chain of custody. Since science is unbiased and sound, forensics is considered a very critical part of any investigation. While witnesses may often be mistaken, have credibility issues, hold a stake in the outcome, have fading memories, or even pass away, forensics "tells the same story" no matter how many times it is tested, or how many years have passed.

Computer Forensics

The field of forensics is so vast that it requires specialists or criminalists at every point of investigation, from tire track analysis, to odontology, to the lands and grooves that make every gun barrel unique. From microscopic evidence and transfer evidence such as fibers and hair, to blood splatter and forensic entomology, there are many fields of specialization within forensic science.

Definition of Forensic Science

Though forensics deals with circumstantial evidence, it is often widely considered as the best and the most compelling evidence that any prosecution or defense lawyer can have in his or her arsenal. Some people suggest that the public's awareness of forensic science might be potentially compromising to law enforcement, producing educated criminals who might be more apt to try and effect a clean crime scene. Experts generally tend to believe that it is nearly impossible to avoid leaving behind trace evidence at a crime scene, even when extraordinary efforts are made to the contrary.
