Antimony processing demands extremely advanced technique. In modern day time, many technics are created for extracting antimony from its ores. The method employed is determined by ore characteristics, as an illustration, when the ore can be a sulfide, an oxide, or a complicated ore, too as to the grade .

Plants for the production of lead are generally referred to as lead smelters. Primary lead production begins with sintering. Concentrated lead ore is fed into a sintering machine with iron, silica, limestone fluxes, coke, soda ash, pyrite, zinc, caustics or pollution control particulates. Smelting uses suitable reducing substances that will

In zone refining, solutes are segregated at one end of the ingot in order to purify the remainder, the antimony can be spread evenly through the germanium. This technique is also used for the preparation of silicon for use in computer chips. source: Was this

Separation behavior of arsenic and lead from antimony during vacuum distillation and zone refining

Antimony Arsenic a b s t r a c t When classifying impurities in commercial pure antimony (Sb, 99.8%), arsenic (As) and lead (Pb) should be brought to the forefront consideration. Due to the known difficulty of As removal through zone refining, it is meaningful to

Generally zone refining is a very time consuming batch technique, in which the refining efficiency for each single pass decreases when the zone passing number increases. To overcome these disadvantages, continuous zone refining was put forward by applying some special structures to realize the function of refining materials without a break.

A method for comprehensively processing noble lead provided and utilizes two instances of vacuum distillation to realize an open circuit of arsenic, lead, antimony and bismuth and the high-efficiency enrichment of precious metals of gold and silver, and can obtain elemental arsenic, a lead-bismuth-antimony alloy, a silver alloy and a copper alloy, respectively.

Antimony Refining Ores. Environmental protection Energy-saving Low cost. Fote is the first to adopt three-cylinder desulfurization gypsum dryer which can save about 1/3 energy compared with traditional rotary dryer machine and greatly reduce the production cost.

Nickel passivation using antimony compounds was first patented by Phillips Petroleum Company, 4 and has since been used for more than 40 years. Numerous studies show that antimony injection alone can reduce the detrimental dehydrogenation effect of nickel by 20-40%, depending on the specific situation.

Primary smelting and refining produces metals directly from ore concentrates, while secondary smelting and refining produces metals from scrap and process waste. Scrap includes bits and pieces of metal parts, bars, turnings, sheets and wire that are off-specification or worn-out but are capable of being recycled (see the article "Metal reclamation" in this chapter).

While antimony concentrates assaying less than 50 antimony may be salable such low-grade concentrates require special arrangements with the smelters. Smelter returns for antimony concentrates are based on a sliding scale which provides for 65 Sb content as the basis.
