The lead and other impurities are absorbed into the bone ash, and the molten silver is drawn off. Silver is extracted from lead ores in large furnaces, a process called cupellation. Most silver is extracted from ores with a froth flotation process, which was discovered early in the 20 th century. In this process, crushed ore is placed in a bath.

When iron ore is extracted from a mine, it must undergo several processing stages. Six steps to process iron ore. 1. Screening We recommend that you begin by screening the iron ore to separate fine particles below the crusher's CSS before the crushing stage. A static screen is used to divert the fine particles for crushing.
