KIVCET-technology for processing of the various plumbiferous raw materials

 

Short description:

 

KTVCET-technology for processing of plumbiferous raw materials is based on a combination of roast smelting furnace-charge processes in a spray state with oxygen, the reduction of the oxide melt in the layer of carbon material and the standing of the depleted liquid-alloy in the furnace, continuously carried out at the single set of original design. The furnace-charge is fir burned off and melted in an oxygen atmosphere and the resulting oxide melt is subjected to carbon-thermal reduction with a high extraction of: lead and precious metals - to black lead, copper - to regulus, zinc - to fume or sullage, sulphur - to combination gas.

 

KIVCET-technology allows processing of both sulphide copper-zinc and zinc-lead raw materials and materials of complex composition: lead-silver and lead-copper-zinc concentrates and oxidized materials.

 

Level of readiness:

 

Under licensing agreements 5 KIVCET-complexes built in Kazakhstan and abroad, construction of a new lead plant for KTVCET-technology of the company «Jiangxi Copper Corporation» and modernization of the lead plant of the company «Zhuzhou Smelter Company» in China is completed.
