How does precious metal refining equipment extract gold?

In addition to copper and resin powder that can be directly extracted from circuit boards, there are other metals that require special refining equipment to extract, especially gold. This year, due to the impact of the epidemic, the price has risen, and the number of people investing in circuit board processing and gold refining increased.

In addition to the main board that can be directly decomposed, the disassembled circuit board also has some non-returnable chips, north-south bridges, memory chips, integrated circuits, and plastic-encapsulated field effects. Collective materials with high gold and silver content in the components are in line with unified treatment. element. Although these components contain gold, they are all gold-plated, and precious metal refining equipment restores these gold-plated pieces. The principle is to use ozone roasting, and the roasting slag uses a solvent carrier, leaching copper, lead tin, and hydrochloric acid medium to leaching gold, platinum, and palladium, and extracting gold, platinum, and palladium. Stripped refined gold.
