In the system of 5-Br-PADAP-Bi-NaOH polarographic catalytic wave system,the trace bismuth in refined antimony can be determined directly and quickly without any separation procedure,and the result is good.

A new measure method of cadmium bismuth copper lead and iron in refined antimony by atomic absorption spectrophotometer was present.

The synthesis of sodium antimonate from antimony concentrates by chloridizing leaching-oxidation and hydrolysis decomposition-alkali synthesis process is investigated.

Determination of trace arsenic in antimony concentrate by hydride generation-atomic fluorescence spectrometry;

To counter the technical difficulty arising in separation of slag and antimony during low temperature smelting of antimony concentrate, a rational technical scheme has been proposed and proved theoretically through practice.

With unity stibnite concentrate and lead-antimony concentrate act as the raw material, sodium sulfide was used to leach antimony concentrate to form sodium thioantimonite solution, sodium pyroantimonate was precipitated by blasting air into the solution.

Based on the plant practice of Chenzhou Mine Limited Company, the factors, such as the flow process, slag type, mixing, bed capability, feed column, blasting and front bed, are analyzed in the process of volatilization smelting on Antimony-Gold concentrate in blast furnace.
