Turn Key Design. Gold ore processing slag ... Borates are also used to facilitate the attack of gold ore at a lower temperature and to make the slag more fluid at the furnace operating temperature thus reducing viscosity The benefits of Dehybor in gold refining are numerous Recover precious metal content with minimal loss to slag.
It has a tapping point for the molten copper and slag. There is normally a waste heat boiler incorporated in the reverb furnace as a lot of heat is applied in this smelting process. The furnace is fired and the enriched ore, which can include limestone and sand, is conveyed and fed into the furnace.
Gold roasting is a process, applicable to refractory ores and concentrates that contain sulfide sulfur, organic carbon, and potentially arsenic. Removal of these compounds is necessary to achieve high gold recovery (>90%) during cyanide leaching. Gold roasting is typically a metallurgical fluidized bed process.

Roasting in Wedge Furnaces. When the first electrolyticzinc plant, that at Trail, B. C., was built, practically no zinc ores had been roasted in the Wedge type of furnace (including the similar McDougal, Herreschoff, and Skinner designs) so far as the writer can learn.
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. Smelting of roasted (calcine feed) or unroasted (green feed) ore concentrate produces matte, a molten mixture of copper sulfide (Cu2S), iron sulfide
