The process has the potential of achieving significant gains in hygiene, environmental controls, and efficiency for the refining aspect of primary lead production. Also attractive about the granulationleachingelectrowinning process is that it could decouple the smelting furnace from refining operations.

Feb 27, 2016· The Miller chlorination process is well know and has been practised for a long time in the gold refining industry. The process consists of chlorine addition into the molten Dore by using an immersed tubing system. Initially there is a slow reaction of chlorine gas with base metals forming volatile compounds.

This process also keeps the lead from oxidizing. The molten lead flows from the blast furnace into holding pots. Lead may be mixed with alloys, including antimony, tin, arsenic, copper and nickel. It is then cast into ingots. Lead exposure. Humans have been smelting lead for thousands of years, poisoning themselves in the process.

A typical pyrometallurgical copper smelting process, as illustrated in Figure, includes 4 steps: roasting, smelting, concentrating, and fire refining. Ore concentration is roasted to reduce impurities, including sulfur, antimony, arsenic, and lead. The roasted product, calcine, serves as a dried and heated charge for the smelting furnace.

and determination of arsenic, antimony and tin, as described in sec­ tion II, 4 and 5. 2. IN TINBASE ALLOYS (a) PREPARATION OF THE SOLUTION The following procedure is designed for the determination of arsenic, antimony, and tin in tinantimony alloys which contain little or no lead. The sample taken should not contain more than 100 mg of

Sep 19, 1995· The invention relates to a process for removing tin, arsenic and antimony from molten lead by means of oxygen or oxygencontaining gas mixtures, which is or are blown into the molten lead by means of at least one gas nozzle (2).

The invention relates to a process for removing tin, arsenic and antimony from molten lead by means of oxygen or oxygencontaining gas mixtures, which is or are blown into the molten lead by means of at least one gas nozzle (2). To avoid damage to the gas nozzle, at least the oxygen outlet region (13) thereof, located in the molten lead (6), is enveloped by an inert gas.

Antimony is not a desirable component in copper electrorefining streams although it is an element often found in normal plant practice. The present work presents data on the extraction of Sb (III) with LIX 1104SM in Escaid 103.
