Quality inspection sampling

Sampling employs scientific methods to randomly select a small portion of the target material that represents the properties of the entire batch. This involves calculations and probability design to ensure that each component and each location has an equal probability of being selected.

Introduction to typical antimony deposits in China

The Xikuangshan Antimony Mine in Hunan Province The Xikuangshan antimony mine in Hunan Province is a typical example of a layered antimony deposit in carbonate strata. Studies have shown that the formation temperature of stibnite is about 250～100℃, and the antimony deposit belongs to a medium-low temperature hydrothermal deposit.

Distribution details of antimony deposits in China

China has four main antimony ore-forming belts, which are connected to four antimony ore belts in the world. The specific distribution details are as follows: (1) South China antimony ore belt; (2) Western Yunnan and Tibet antimony ore belt; (3) Qinling-Kunlun Mountains antimony ore belt; (4) Changbai Mountain-Yinshan-Tianshan antimony ore belt

Beneficiation of stibnite ore

The composition of single antimony sulfide ore is relatively simple, with the main metallic mineral being stibnite. Some ores also contain a small amount of native antimony, while the gangue minerals are mainly quartz and calcite.

Beneficiation of stibnite ore

Currently, stibnite ore is generally processed by flotation (or a combined gravity-flotation method), using xanthates or thiocarbamates as collectors, lead salts as activators, and pine oil as a foaming agent. After treatment in a weakly acidic medium with a pH of around 6.5, a high-grade antimony concentrate can be obtained.
