Antimony Smelting - Mineral Processing

19/03/2017  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. The writer was then asked to take charge of the erection and control of this first plant for regulus production in China and has, since then, been more or less connected with the antimony ...

Worker Health Study Summaries - Antimony Smelters

Antimony Smelters (Antimony Exposure) 1997. Study Background. NIOSH studied 1,014 antimony smelter workers. We used company and government records to do the study. Purpose of the Studies.

Antimony process - American, Smelting Refining

As shown by the flow sheet, antimonial lead scrap such a's scrap battery plates, etc. are smelted and reduced in situ to yield soft lead and an antimony slag. This smelting and reducing process is suitably performed in a furnace of the reverberatory type. The antimony slag is transferred to a blast or reverberatory furnace to which is also added slags from the fuming and converter furnaces hereinafter referred to and the combined slags smelted

Antimony - Wikipedia

Antimony is a chemical element with the symbol Sb (from Latin: stibium) and atomic number 51. A lustrous gray metalloid, it is found in nature mainly as the sulfide mineral stibnite (Sb 2 S 3).Antimony compounds have been known since ancient times and were powdered for use as medicine and cosmetics, often known by the Arabic name kohl. Metallic antimony was also known, but it was

In these tests, Avitone A was also added to the refinery cell, but ...

Lead smelting - Wikipedia

Plants for the production of lead are generally referred to as lead smelters.Primary lead production [clarification needed] 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 combine with those oxidizing ...
