also used for production of antimonial lead, which is an important product of the secondary lead smelter. A blast furnace charge containing used or discarded battery plates, type metal and bearing metal is reduced to lead bullion. The bullion is then reﬁned in reverberatory furnaces to meet speciﬁions. Lead–antimony
Antimony can be recovered in the residues from the lead refining process. The main endoflife recycling option is from spent leadacid batteries mainly recovered from old vehicles. PRECIOUS METALS REFINING Visit site. Business Units. Catalysis. Automotive Catalysts
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,
Refining Primary Lead by Granulation–Leaching–Electrowinning
The pyrometallurgical Lead refining process is one of the most important procedures of lead battery recycling. This process is also known as "Softening of Lead" because the metal is softened after the removal of some impurities which are present in the raw lead coming from lead battery recycling would be more correct to call only the process of antimony, arsenic and tin removing
Antimony Smelting Mineral Processing & Metallurgy
The history of the antimony industry of China dates back to 1897 when the Tai Shing Co. was formed, under contract with the Hunan Bureau of Mines, for the smelting of the ore to crude and in 1908 the Wah Chang Mining & Smelting Co. was formed for the smelting and refining of the ore and crude to regulus.
Lead Refining Plant, Lead Refining Technology, Recycled
Recycled Lead Processing Refining. The removal of impurities and other metals from the crude Lead (S, Cu,Ni, As, Sb, Bi, Ag, Au, etc.) is Refining. The refining process is applied in several steps in kettles with addition of specific agents alternatively smaller quantities are processed by electrolytic refining.

Lead Alloying Plant, Lead Metal Alloying Process, Lead
Lead alloys can be extruded into pipes, bars, channels, and rods. In our process of Lead Alloying, we manufacture varieties of Lead Alloys based on the customer specifiions. We are capable of manufacturing the following types: Calcium – Lead Alloy Antimony Selenium Lead Alloy 2.5 Antimony Lead Alloy 3.0
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.
Lead Metal Refining and Alloys. For more than 150 years, we have provided premium, highquality lead metal and lead alloys. Since 1991, our secondary smelter has met our customers'' needs with highpurity secondary lead and numerous custom lead alloys.

Lead Refining Dross Metalcess. Refining dross is the result of lead refining process where impurities like copper, tellurium, arsenicantimonytin, silver, zinc and bismuth in sequence from lead bullion.
as candlesticks, dinnerware, eating utensils, and so forth. After the leadacid storage battery was developed at midcentury, lead battery plates hardened with antimony were noted to last longer in service than pure lead plates. A military use also appeared in the 19th century when a brittle lead alloy hardened with 10 to13 percent antimony was
Antimony is chalcophile, occurring with sulfur and the heavy metals, lead, copper, and silver. Over a hundred minerals of antimony are found in nature. Stibnite (Sb 2 S 3) is the predominant ore mineral of antimony. The most important use of antimony metal is as a hardener in lead for storage batteries.

from the production of lead, copper, gold, and antimony . The large production volumes, especially for copper and lead, mean that these residues have the potential to replace a large portion of the primary antimony production . Secondary antimony sources also include endoflife products such as leadacid batteries, plastics with anti
The method of refining of antimony leadantimonic alloy
The invention relates to ferrous metallurgy and can be used in the processing of battery scrap and secondary lead alloys.
