preferential flotation of antimony ore. Preferential flotation is a selective process where certain minerals are floated preferentially over others. In the case of antimony ore, stibnite is ...
The flotation of gold-bearing ores is classified according to ore type (i.e. gold ore, gold copper ore, gold antimony ores, etc.), because the flotation methods used for the recovery of gold from different ores is vastly different. 17.2 GEOLOGY AND GENERAL MINERALOGY OF GOLD-BEARING ORES
For fine-grained oxidized ore or refractory oxidized ore, the ore is first reduced to metallic antimony, and then processed using conventional flotation methods. This process requires adding a chlorinating agent and heating in the presence of a solid reducing agent, so that the antimony in the ore is precipitated in the form of chloride …
Flotation is the most important extraction method for antimony deposits. Antimony sulfide deposits are easy-to-float deposits, and flotation methods are mostly used to improve the crystal position of …
The flotation process is widely used in the mining industry to separate valuable minerals from ore, and the process relies on using specific types of ore. Usually used to concentrate various sulfide minerals, phosphates, and oxide minerals also need to be concentrated by flotation machines.For example, gold ore, silver ore, copper ore, …
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.
