1. Electronic components containing gold: some contacts such as video recorder, electric singer, measurement instrument, analyzer, computer and other instruments and electrical appliances. The lead and line board also contain gold. 2, alloy containing gold: The content of gold in the alloy is very high. There are also many low -gold alloys that are more likely to be forgotten after use and recycle them as general metals. 3, jewelry waste, anode mud, battery, solder alloy, dental alloy, gold -plated device and chemical, electronics, electroplating, and jewelry, etc., all contain gold. The classification of gold: 1, mineral gold: Also known as the synergy gold, produced in mines and gold mines. The quartz is caught in the gap between the rocks. The ore is mining, crushed, and washed. Large gold can be picked directly, and the small grains can be dissolved with mercury. 2, sand gold: It is produced at the bottom of the river or low -lying area, so the stone sand is mixed together, and the gold that is washed out. Sand gold originated in the mine, because the gold ore was exposed to the ground. After a long wind and rain, the rocks collapsed in the north wind, and the gold was separated from the sand and the water. Deposition is a gold -containing layer to form sand gold. 3, cooked gold is the gold that has been smelted and purified after smelting and purification. Generally, the purity is high and the density is fine. Some can be directly used in industrial production. Common gold bars, blocks, ingots, and various accessories, utensils, gold coins, and industrial gold silk, pieces, boards, etc.

You can also provide more effective information so that I can answer it better. BleaknHello, I am glad to answer it for you. You can go to some precious metal recycling companies for cooperation, where there is it. Gold (GOLD) is a single form of chemical element gold (AU). It is a soft, golden, corrosive precious metal. Gold is one of the rare, precious and extremely valued metals. Internationally, gold is generally based on ounces. In ancient China, "two" was used as a gold unit, and it was a very important metal. It is not only a special currency for reserves and investment, but also an important material for the jewelry, electronics, modern communications, aerospace and air industry and other departments.nCan I refine the gold?nAnswer dear, copper cannot refine the goldnCan I ask the waste mobile phone?nAnswernQuestions about those electronic products that can be trained for goldnThe answers that can refine gold are: battery contact, SIM card, computer motherboard, CPU, memory barriernAsk if the circuit board of the waste TV can be refinednAnswernI hope my answer can help you.
