A process and apparatus for the removal of arsenic values from an ore concentrate includes the steps of leaching the concentrate with a solution which dissolves the arsenic, separating undissolved residue therefrom, acidifying the arsenic pregnant solution to precipitate arsenic and other mineral values as insoluble salts and treating the arsenic barren solution to regenerate sulfur and sodium ...
Froth Flotation Method JXSC Machine
FlotationConcentrate RoastingCalcination Cyanidation The process is often used to treat insoluble gold-arsenic ores, Gold-Antimony ores and gold-pyrite ores with high sulfide content. The purpose of roasting is to remove arsenic and antimony which are harmful to the cyanidation process. Thermal treatment of flotation flotation concentrate
3 Antimony Ore Beneficiation Process
Antimony ore can be divided into antimonite, cubismite, antimony ochre, etc. Due to the difference in the nature of the ore, the process used is also different. Commonly used beneficiation processes include manual separation, gravity separation and flotation . This article briefly introduces these three commonly used antimony ore beneficiation processes.

PROCESSING At least six principal methods are or have been used to extract antimony from its ores.Of the sulfide ores or concentrates thereof made by the froth flotation process, those that contain from 1.5 to 25 percent antimony are roasted to produce oxides, and those with from 25 to 45 percent...
Antimony Recovery from EndofLife Products and Industrial
Feb 08, 2016 Kanarskii et al. investigated the concentration and isolation of antimony and arsenic in Sb-As-bearing gold ores by flotation. They demonstrated the flotation separation of antimonite and arsenopyrite into separate products, thus increasing process efficiency and profit by improving the gold recovery rate and reducing the consumption of cyanide.
