Abstract. Electrodeposited antimony can be treated with sulfuration–volatilization technology, which causes antimony to volatilize in the form of antimony sulfide. During this process, gold is enriched in the …
There are many varieties of antimony ore, including antimonite, antimonite, antimony, antimony ochre, etc. Depending on the properties of the ore, the optional beneficiation processes include manual selection, gravity separation and flotation. The density, color and metallic luster of stibnite are significantly different from those of gangue ...
Most antimony ores in China are found in Hunan and Guangxi, and the reserves are abundant. Antimonite ore is processed by hand-picking–flotation or …
The copper, insoluble in water, that is in the calcined ore, is removed by the use of tower liquors, and under the action of this solvent a considerable proportion of the arsenic, antimony and bismuth that remained in the calcined ore is also dissolved. This increases the proportion of these elements that is already present in the tower liquors.
Antimonite ore is processed by hand-picking–flotation or heavy medium separation–flotation to pick out lump ore, rich lump ore, and concentrate that will go into the smelting process. Antimony smelting is done through the pyrometallurgical process or the hydrometallurgical process, but mostly the pyrometallurgical process.
The flotation and mining sites were far away from the smelting site on the second principal coordinate axis. The reason may be that the antimony in the ore was released during the smelting process, which enriched more lead in the waste slag, resulting in a higher lead content at the antimony smelting site than at the mine and flotation sites.

Fig. 1 shows that the antimony flotation process includes 5 parts: roughing, scavenging Ⅰ, scavenging Ⅱ, cleaning Ⅰ, and cleaning Ⅱ, respectively. In the roughing cell, the input pulp mainly comes from the output pulp of the gold roughing cell. Combined with the flotation reagents, most of the antimony ore particles are separated from the …
200 antimony and azoque-antimony mineralization occurrences [3], a lot of quarts-gold-antimony deposits, including the Solonechenskoe and Zhipkoshinskoe deposits with average 4.5 – 18 % antimony and economic gold ore grade have been explored in the area. Antimony is a valuable mineral component in gold-bearing ores though it is an …
Description. Antimony is a silvery- white metal that is found in the earth' s crust. Antimony ores are mined and then mixed with other metals to form antimony alloys or combined with oxygen to form antimony oxide. Little antimony is currently mined in the United States. It is brought into this country from other countries for processing.
Ninety percent of the world's copper, lead, zinc, molybdenum, antimony, and nickel are produced by processes employing concentration of ore by flota tion. Although the processing of mineral ores is by far the largest use of flotation separation, numerous other processes have been developed for the separation of other materials.

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. In flotation of gold-containing base metal ores, a number of modifiers normally used for selective flotation of ...
Sodium diethyldithiocarbamate (DDTC) is a typical organic flotation reagent that has been widely used in the process of antimony ore flotation. Combined pollution with DDTC and Sb is common in the soils at antimony mining areas. At present, the mechanisms of the combined pollution of Sb and DDTC are poorly understood, so …
Attention to these four points can greatly improve the flotation efficiency of tin ore. Firstly, please select the appropriate collector and adjust its dosage according to the characteristics of the ore. Second, control the pH value and add appropriate activators and inhibitors. Third, ensure proper pulp density and stirring speed.

A tungsten-antimony gold mine in China has obtained good results with camphor oil in the priority flotation process of Antimony-Gold ore. Regulator: Lime is a commonly used medium regulator, and also an effective inhibitor of sludge coagulant and pyrite. It also has a certain inhibitory effect on gold sludge.
antimony ore as oxide or sulphur antimony is effective on determination of the method. In general, gravity concentration is mostly applied for oxide and coarse-grained ores, where flotation method ...
Especially for sulfide antimony ores, the most common beneficiation method is flotation. Therefore, antimony ore consisting of stibnite mineral obtained from Tokat-Turkey region was used in this study. Due to the low antimony (5.06%Sb) and the high Arsenic (1.38%As) content, it is an important requirement to increase the Sb content of this ore ...
