The project implementation plan can be divided into two categories:
One is to construct a small-scale smelter specifically for processing aluminum group metals according to the proposed process flow;
The other is to utilize the existing processes and equipment of a non-ferrous metal smelter to enrich and extract group metals in the non-ferrous metal smelting process.
Wet leaching of precious metals: The essence of wet leaching technology is to directly dissolve aluminum group metals from a carrier using hydrochloric acid and a strong oxidant or other special chemical reagents (such as cyanide), and then further enrich and extract platinum group metal products from a low-concentration bath.
Currently, various pyrometallurgical technologies under research can all achieve the goal of recovering platinum group metals. However, the complexity of the processes, technical and economic indicators, ease of engineering implementation, and environmental impact vary greatly among different methods.
