Rotary furnaces are batch furnaces, and hence can be operated in stages to produce lowimpurity bullion for refining to pure lead, or they can entirely reduce the charge to recover all metal values for production of leadantimony alloys. Rotary furnaces typically use Na2CO3 and iron as fluxes that produce a fluid, lowmelting slag.
Smelting is the process by which rough lead bullion is produced from lead concentrate. .... as gold and silver, oxides of antimony, arsenic, tin, and copper. ... Harris softening utilizes the same reagents as kettle softening, and also requires low levels of.
Copper, Lead and Zinc Smelting and Refining The major hazards are exposure to ore dusts during ore processing and smelting, metal fumes (including lead, arsenic and antimony) during smelting, sulphur dioxide and carbon monoxide during most smelting operations, noise from grinding and crushing operations and from furnaces, and heat stress from the furnaces.
The basic objective of refining is to remove almost all traces of Copper (Cu), Antimony (Sb), Arsenic (As), and Tin (Sn) since, as per specifications, Soft Lead cannot have more than 10 .
Our Antimony Trioxide range is delivered from stibnite metals or as a sideeffect of lead refining and generation. This range is utilized in flame retardant definitions for plastics, rubbers, materials, paper and paints. Further, it can be utilized as an added substance in glass and fired items and as an impetus in the compound business.
Dross A scum formed on the surface of molten metal. Dross refers to the lead oxides, copper, antimony, and other elements that float to the top of the molten lead. Dryer A chamber that is heated and that is used to remove moisture from leadbearing materials before they are charged to a smelting furnace.

Antimony oxide is a white powder and is derived from the mineral stibnite (antimony sulfide) or produced by the oxidation of antimony metal or as a byproduct of the refining or antimoniallead alloys. It sometimes behaves as a metal and sometimes as a non metal.
Vacuumrefining experiments were carried out on copper matte melts, containing 35 to 73 pct Cu, to measure the removal rates of lead, bismuth, arsenic, and antimony over the temperature range of 1373 to 1523 K under pressures in the range of 50 to 130 Pa. High rates of refining, controlled by mass transport in the liquid phase, were achieved for all impurities in melts containing up to 65 pct Cu and for .

Sep 23, 2013· In fact any copper in a lead or zinc concentrate is generally problematic in the smelting/refining processes and would most likely incur a penalty charge (see more on penalties below). Usually lead and zinc bearing concentrates are sold as a separate product but there is a market of a mixed lead/zinc concentrate, commonly referred to as "Bulk ...
Ingot lead can also be known as lead pigs, bullion or bar lead and range in size from 10 LB ice cube tray ingots to 70 LB large ingots. For more information please see the dimensioned line drawings and renderings below to help you decide on the ingot sizing that suits you best.
Oct 19, 2017· Metallic lead that results from the roasting and blast furnace processes still contains significant contaminants of arsenic, antimony, bismuth, zinc, copper, silver, and gold. The melt is treated in a reverberatory furnace with air, steam, and sulfur, which oxidizes the .
Refining process antimony chirogullegembe Refining process for removing antimony from lead bullion An improved process for refining lead bullion containing antimony in which the bullion is initially heated in a refining vessel to about 25 F 14 C above the bullion melting point and is thereafter kept.
Bottom‐up process design is performed for a new antimony white fuming approach from antimony‐rich lead refining residues. Thermochemical modelling is used to evaluate process boundaries regarding temperature and slag composition allowing the fuming of qualified antimony .
