Gold producing and refining device

Abstract

The invention discloses a gold producing and refining device which comprises a smashing barrel and two smashing rollers; the two smashing rollers are adjacently mounted at the port of the smashing barrel and are driven by externally connected driving equipment; a preliminary screening device is mounted in the smashing barrel; and a secondary screening device is mounted on the outer side of the smashing barrel. Through joint matching of the preliminary screening device and the secondary screening device, a circuit board is smashed, the smashed circuit board is screened through multiple steps, residual large and small plastic plates are effectively removed, and a large amount of metal residual blocks can be kept. Compared with the existing manual stripping, the gold stripping efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of gold refining, in particular to a gold production and refining device. Background technique [0002] Gold (Gold) is the elemental form of the chemical element gold (chemical element symbol Au), which is a soft, golden yellow, corrosion-resistant precious metal. Gold is one of the rarer, most precious and highly valued metals. In the world, gold is generally measured in ounces. In ancient China, "two" was used as the unit of gold. It is a very important metal. It is not only a special currency used for reserve and investment, but also an important material for jewelry industry, electronics industry, modern communication, aerospace industry and other sectors. [0003] At present, most of the gold is extracted through gold mines. In daily life, some discarded household appliances are also rich in gold, but because people cannot dissect them normally, when the waste products are discarded, the gold in the e...

Problems solved by technology

[0003] At present, most of the gold is extracted through gold mines. In daily life, some discarded household appliances are also rich in gold, but because people cannot dissect them normally, when the waste products are discarded, the gold in the electrical appliances is mainly concentrated in the chip. Manifold chip cpu IC is a gold-containing material with gold inside. The place indicated by the green arrow is the gold-plated part. If it is buckled, the chip will partially remain on the circuit board, and it will be laborious to cut it with scissors. For this reason, we propose a gold production and refining device
