Waste electronic waste precious metal refining equipment
In recent years, with the rapid development of the electronics industry, the replacement rate of home appliances such as mobile phones and computers has become faster and faster, and many waste home appliances have been discarded casually. According to experts, these discarded electronic wastes still have good utilization value. For example, gold-containing components can be picked out from some old mobile phones, computers and other parts to extract gold. Hundreds of thousands of tons of gold-containing waste need to be processed every year. . In 1 ton of electronic boards, 0.45 kg of gold, 1 kg of silver, 130 kg of copper, and 20 kg of tin can be separated. “Electronic waste” has become an industry that hides huge profits.
With our process, the recovery rate can reach 99%, and the purity is 99.9%. According to our many years of refining experience, 1 ton of electronic boards can be refined to 350 grams of gold, 2 kilograms of silver, 120 kilograms of copper, 25 kilograms of tin, 10 kilograms of palladium capacitors, 10 kilograms of nickel-containing parts, 400 kilograms of bare boards, etc. Detailed content, price list), and the extraction of gold and silver from the leftovers of the electronics factory is even more impressive.
3. Recycling value and status in production.
The utilization value of precious metal secondary resources is increasing, mainly because:
(1) Humans have produced a large amount of precious metals (gold, silver, platinum, palladium, rhodium, iridium)
(2) The resources of precious metals are scarce, especially the industrial reserves of gold and silver are relatively small.
(3) The precious metal content is much higher than that of the raw ore, generally hundreds of times more.
4. Gold production, consumption and main application fields.
Gold is a metal developed and utilized by humans. Because it mostly exists in the state of natural metal, easy to pick, easy to select, and easy to process. At the same time, it has a lovely golden yellow color, which can be preserved for a long time without changing. The jewelry industry with a large demand for gold accounts for about 85% of production and processing on average, followed by the electronics industry accounting for about 6%-6.5% and dentistry accounting for about 2%. Aerospace, aviation and other industries, and medals, commemorative medals, government Currency, gold is an important hard currency, and all countries have a large amount of reserves.
