Processes for extracting precious metals such as gold, silver, platinum, and palladium from tailings

This process offers different treatment methods for tailings with varying impurity levels.

The following section details the process flow using tailings containing coarse-grained free gold as an example.

Although the crude antimony slag-making purification method is not the final product forming process, it is a core technology to ensure product purity and quality grade and enhance product value.

After crude antimony is purified and refined by the slag-making method, a series of subsequent processing steps are required to obtain high-quality products.

This process is mature, economical, and efficient, and is an indispensable refining step in modern antimony smelting.
