Antimony Recovery from End-of-Life Products and

08/02/2016 Complex antimony minerals often require adapted flowsheets in order to ensure the recovery of antimony and the other main metal constituents. The last primary producer of antimony in the U.S.A. (Sunshine Mining & Refining Company) was mining the complex copper-silver-antimony sulfide: freibergite (Cu,Ag) 12 Sb 4 S 13 . This mine produced both silver and antimony concentrates

Recovery of Antimony: A Laboratory Study on the Thermal

antimony oxide to metallic antimony is achieved by heat-ing and the addition of carbon in a reverberatory furnace. Volatilization of antimony can be reduced by the addition of an alkaline flux but it cannot be eliminated [20] and volatilized antimony oxide is recovered in flues, condens-ing pipes, bag houses, precipitators, or a combination [21].

Antimony: Chinese smelters focus capacity to process Au

Chinese antimony producer, Guangxi Wanshizhi Rare and Precious Metals Technology, kicked off a new nonferrous multi-metal recovery project in early March 2021. The project’s annual design capacity is for 20kt refined antimony, 10t gold ingot, 100t silver ingot, planned to consume 40ktpy Sb-Au-Ag concentrate and 4ktpy sludge.

01/03/2014 A process for antimony recovery from stibnite concentrate is proposed. Consequently, antimony metal and a melt mainly containing sodium carbonate and resultant sodium chloride were obtained. After liquid antimony was discharged from the bottom of a rotary kiln, the melt (mainly Na 2 CO 3 and NaCl) was discharged from the reaction zone and reused as flux. Table 11 shows the results of

Antimony and Antimony Compounds Grund - Major

Antimony metal is recovered from ore primarily by pyrometallurgical techniques. Because rich ores are becoming rare, greater recourse is being taken to intermediates in processing and metal industries. Hydrometallurgical processing is suitable for some ores containing precious metals and is used by the Sunshine Mining Co. (USA). Refining and fine purification techniques are used for production
