antimony smelting furances

CN102787246A

The invention relates to a smelting production method of antimony trioxide The method includes the following steps of: raising the furnace temperature of a smelting furnace to 700DEG C-900DEG C, pushing an antimony ingot into the furnace by a mechanical arm and then stopping heating, and introducing air into the furnace body, letting the oxygen in the air and the antimony ingot undergo an ....

The metallurgy of antimony

3 Uses and applications Antimony trioxide, Sb 2 O 3, is the most important antimony compound producedToday, antimony trioxide is produced by volatilizing antimony metal in an oxidizing furnace It is used in halogen compound flame retarding formulations for plastics, paints, textiles and rubber...

Cupellation

Cupellation is a refining process in metallurgy where ores or alloyed metals are treated under very high temperatures and have controlled operations to separate noble metals, like gold and silver, from base metals, like lead, copper, zinc, arsenic, antimony, or bismuth, present in the ore The process is based on the principle that precious metals do not oxidise or react chemically, unlike the ....

Antimony process

In the fuming furnace there is produced, in addition to the volatilized antimony oxide, a slag and an antimonial lead metal The slag is returned to the furnace in which the original antimony slag from the scrap smelting furnace is treated while the antimonial lead metal is treated in one of two ways according to its copper content...

Viscosity Property of Gold

Viscosity of slag determines the production efficiency, energy consumption and distribution of elements between metal and slag, which is very important for pyrometallurgy Slag of gold-antimony ore blast furnace smelting has seldom been studied...

Melting antimony

I have a few hundred pounds of pure lead along with some pure tin I would like to alloy in enough antimony to get to 15 to 16 BHN I can purchase the antimony from Rotometals, but melting it is where my question aris The melting point for antimony is about 1100 degre I know that my casting furnace won't be satisfactory for this purpose...

Lead smelting

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...
