sumption of antimony. 4. The mineral processing of antimony Originally antimony was mined and hand sorted to effect concentration. Since the bulk of primary production is in China, where labor is plentiful and cheap, surprisingly, hand sorting still finds a large application. However, in recent years, many other unit operations are used in the mineral processing of antimony.
He also contemplates antimony removal during the refining process to remove most of the antimony due to the fact that where arsenic and antimony content of the lead is above about % by weight, relatively large quantities of antimony as well as arsenic are incorporated into the tellurium during the detellurizing procedure. The sodium or potassium or mixtures thereof

The disclosure relates to a process for refining of copper bullion comprising arsenic and/or antimony in order to enable extraction of the metal values bound in the copper bullion. The process comprises two separate metallurgical process steps wherein the first step comprises selective conversion of elements having high affinity to arsenic and antimony and the second
· During zone refining process, As concentration in the whole bar was considerably reduced from 456 ppm to below 150 ppm (and as low as 50 ppm at the end of the bar) after only one zone pass by adding wt.% Al into the Sb, which is contributed to the floating of formed AlAs intermetallic. Moreover, opposite to the normal As distribution, the

Refining and alloying operating temperatures range from 320 to 700°C (600 to 1300°F). Alloying furnaces simply melt and mix ingots of lead and alloy materials. Antimony, tin, arsenic, copper, and nickel are the most common alloying materials. Refining furnaces are used to either remove copper and antimony for soft lead production, or

Electrolytic refining. Electrolysis, or electrolytic refining, is a technique that is already in use for the extraction and purification of metals, and it is a much more costeffective and efficient technique than traditional heatbased smelting methods. Indeed, it was the discovery of the HallHéroult electrolytic process more than a hundred years ago that transformed aluminium from

The fire refining processes for antimony with the objective to primarily remove tin and lead as much as to receive respective residuals of % and % in the metal are multistage processes, associated with significant antimony losses during the slag phase, particularly when deep treatment for tin removal. This effect is observed due to the very close thermodynamic
