Three Methods To Antimony Ore Beneficiation And Processing
May 22, 2022Antimony sulfide deposits are easy-to-float deposits, and flotation methods are mostly used to improve the crystal position of the ore. In the meantime, stibnite often uses lead salts as activators first, and also uses copper salts or both lead salts and copper salts, and then uses collectors for flotation.

How Arsenic, Antimony Silver Compounds Affects Leaching
By the preliminary treatment the silver, and in part at least, the antimony and arsenic, are reduced to the metallic state, and are so found. The reduction is accomplished by the nascent hydrogen resulting from the action of caustic soda on the aluminium according to the following equation: (1) 2Al + 2NaOH + 2H2O = Na2Al2O4 + 6H."
