Nov 01, 2015· The biosorption of gold from discarded computer microprocessor (DCM) leachate solutions was studied using chitin as a biosorbent. The DCM components were leached with thiourea solutions, and two procedures were tested for recovery of gold from the leachates: (1) biosorption and (2) precipitation followed by biosorption.
Oct 10, 2019· Recycling provides a much richer resource than the extraction of material from ore. In fact, the Electronic Recyclers International (ERI) quotes the EPA as saying: One metric ton of circuit boards can contain 40 to 800 times the amount of gold and 30 to 40 times the amount of copper mined from one metric ton of ore in the US.
Gold is usually found alone or alloyed with mercury or silver, but can also be found in ores such as calaverite, sylvanite, nagyagite, petzite and krennerite. Most gold ore now comes from either open pit or underground mines. The ores sometimes contain as little as 5/100 of an ounce of gold .
The parts that contain gold in the computer are rams, motherboard, microprocessor, hard drive, cdROM drive, gold plated connectors used on motherboards and drives. Most of the gold from computer parts is extracted from the chips mounted on the motherboard, rams and the logic cards of the hard drive, cdROM, and the microprocessor.
Extraction. Chemical extraction of Gold, Silver, Platinum, Palladium and Rhodium can be extracted from such components and the removal and disposal of hazardous materials including Mercury, Cadmium, Beryllium Oxide and Batteries (NiCd, Lithium etc.) is also undertaken.
Seventeen metric tons of gold ores will yield approximately .51 to 85 grams of gold that''s to 5 grams of gold per metric ton depending on the location of the mine. In comparison, a ton of obsolete phones can yield as much as 280 grams of gold, about 140 grams of platinum and palladium, and 140 kilograms of copper.

Jun 19, 2019· I extract gold from 10 laptops as we know that each laptop contains 60 mg of gold in it so after extraction I got 500 mg of Gold from these laptops. In this way, I recycled the old laptops gold flakes into the original gold. More laptops will extract more Gold in this way. This process does not need an expert, only by taking some safety ...
In this Instructable, I will show you how to extract gold from computers using products most people have lying around in their homes. The way I extract the gold is relatively straightforward and pretty easy, but the chemicals used are very dangerous and should not be performed without proper knowledge and equipment. This process is not supposed to be lucrative.
In underground mining situations, the mine roof conditions, ground support system, and ventilation are important factors in determining the extent of the blast area. In an underground gold mining operation in Nevada, blasting in a drift caused a roof fall in another drift situated about 25 ft below the blasted drift.
Answer (1 of 1): I know 2 methods to extract gold from processors: First one is disconnect the tabs and strip them in cyanide. Second method is to burn the whole thing; collect the copper and gold out of the ash; then get the gold from the copper. Both methods are very dangerous. The amount of gold you will obtain this way might not be worth the effort and the information in the ...

Aug 20, 2019· Canadian researchers have developed a largescale economical method to extract hydrogen from oil sands (natural bitumen) and oil fields. This can be used to power hydrogenpowered vehicles, which are already marketed in some countries, as well as to generate electricity. The process can extract hydrogen from existing oil sands reservoirs,...
Removing the goldbearing rock from the ground is just the first step. To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel.
solvent extraction is a continuous operation. The gold content of the feed can range from about 20 per cent to 99 per cent. Suitable feeds include silverrefining anode slimes, gold electrowinning cathode sludge, zinc precipitation filtrates, dorè bullion and jewellery scrap. Materials with variable gold .
The primary methods used to extract minerals from the ground are: Underground miningSurface (open pit) miningPlacer mining The location and shape of the deposit, strength of the rock, ore grade, mining costs, and current market price of the commodity are some of the determining factors for selecting which mining method to use.
Mar 01, 2016· Gold is a incredible conductor of electricity, which is why it''s used as a coating in a lot of electronics, especially parts where data transfer happens like RAM.
The mining of alluvial deposits and, later, lode or vein deposits required crushing prior to gold extraction, and this consumed immense amounts of manpower. By ad 100, up to 40,000 slaves were employed in gold mining in Spain. The advent of Christianity somewhat tempered the demand for gold until about the 10th century.
