Aug 12, 2022· Concentrates containing higher antimony contents (>25%) are not treated via conventional volatilization roasting as the material is likely to melt (causing local incomplete sulfur removal), and formation of antimony glass (a mixture of undecomposed stibnite, antimonates, arsenates, and sulfates) may be inevitable, which in turn results in …

Antimony is classified as a critical/strategic metal. Its primary production is predominated by China via pyrometallurgical routes such as volatilization roasting—reduction smelting or direct reduction smelting. The performance of most of the pyro-processes is very sensitive to concentrate type and grade. Therefore, technology selection for a greenfield plant is a …

Liquation. Liquation is a metallurgical method for separating metals from an ore or alloy. A mixture of metals is melted together with a third, after which the mixture is separated by liquid extraction. This method was largely used to separate silver from copper using lead, but it can also be used to remove antimony minerals from ore, and ...

liquation, technique for separating constituents of an ore, a metal, or an alloy by partial melting. When the material is heated to a temperature where one of the constituents melts and the other remains solid, the liquid constituent can be drained off. It was formerly used for extracting antimony minerals from ore and for separating silver from copper with the use …
