Antimony and arsenic substance flow analysis in antimony
By taking antimony and arsenic as the objective elements, the mass balance and substance flow charts based on the production system were established, 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 Minerals Free Full-Text Preparation of Antimony

Removing antimony from waste lead storage batteries alloy
In the process of electrolytic refining, the required antimony content of lead anode plate is approximately 0.4–0.7 wt%. When antimony content of lead anode plate is more than 1.2 wt%, antimony firmly adheres to the residual lead anode plate during the refining process, which leads to difficulty in cleaning.The invention discloses an oxygen-enriched molten pool antimony refining production process, and belongs to the field of smelting of nonferrous metal. The process comprises the following steps: 1) batching: raw materials are uniformly mixed according to a mass ratio to obtain a mixture; 2) granulation: the uniformly mixed mixture is prepared as spherulites; Oxygen-enriched molten pool antimony refining production process

Metal Smelting and Furnace Tapping SpringerLink
The present topic “Metal Smelting and Furnace Tapping” provides JOM readers with an interesting update on these high-temperature pyrometallurgical processes. Metal smelting is a fundamental process in pyrometallurgical metal production. The process parameters and furnace operating conditions need to be adjusted and optimized for theAn integrated two-stage metallurgical process has been developed to process concentrates from the Olimpiadinskoe deposit, which contain high levels of antimony and arsenic. The optimal parameters for the alkaline sulfide leaching process of the initial concentrate from the Olimpiadinskoe deposit were determined to achieve the Development of a Two-Stage Hydrometallurgical Process for Gold–Antimony

Resilience in the antimony supply chain ScienceDirect
The antimony diversity of supply of both mining and refining is low. • Almost 70% of Sb is mined as by- or co-product. • Companion metals can both have higher and lower resilience. • An additional 25% of Sb production comes from post-consumer recycling. • Stockpiling has played a role in dampening and exacerbating supply disruptions.Contribute to chengxinjia/sbm development by creating an account on .sbm/sbm antimony ore milling process.md at main

Antimony Metallurgy SpringerLink
Antimony Metallurgy. Antimony metallurgy is the technology that extracts antimony metal from antimony ores or produces antimony compounds. Antimony was discovered in the ancient time, and its name was derived from antimonite. In 1604, a process was invented to extract antimony and antimony sulfide as described by B. The electrorefining process of the non-commercial Cu anodes was tested on the enlarged laboratory equipment over 72 h. Cu anodes with Ni content of 5 or 10 wt.% and total content of Pb, Sn, and Sb of about 1.5 wt.% were used for the tests. The real waste solution of sulfuric acid character was a working electrolyte of different temperatures (T1 Electrorefining Process of the Non-Commercial Copper Anodes
