Oxygen Bottom-Blowing Copper Smelting Process (SKS/BBS)
Solved Problem

Oxygen Bottom-Blowing Copper Smelting Process (SKS/BBS) is a new bath smelting process   independently researched and developed by ENFI/TOMINE. Oxygen-enriched process air is injected   in a high velocity into the bath via lances positioned at the bottom of the rotary horizontal     SKS/BBS furnace, so as to complete chemical reactions with concentrate. With unique       kinetic conditions, the process is specially featured with wide adaptability to different   feeds, high chemical reaction heat efficiency, low energy consumption, high metals    recovery, high impurities removal efficiency, low capital cost, low operating cost and      preferable  environmental  performance  among  other  merits, thus  making  it  rank    among the world’s leading level. TOMINE has engineered 18 SKS/BBS smelters with  concentrate throughput above 7000kt/a.

Flow Chart

TOMINE has  has provided universal engineering services from engineering test, project consulting, engineering design, EPC service to project supervision, etc. for more than one hundred of copper smelting compa- nies worldwide, making it the only one engineering corporation in the industry being capable of designing smart plants and providing such complete set of large equipment as metallurgical furnace and waste heat boiler, etc., as well as DCS.

TOMINE  has  rich engineering experience  in comprehensive  recovery from copper sulfide ore, copper oxide ore, complex copper-nickel  mix ore and secondary copper materials, and  has mastered multiple copper smelting technologies including flash smelting, top-blowing smelting, bottom-blowing smelting, side-blowing smelting, pressure leaching, roasting – leaching, etc. TOMINE has designed the world’s largest copper smelting operating lines by using top-blowing technology,flash technology and oxygen bottom-blowing technology, with the maximum concentrate throughput for single operating line reaching more than 1600kt/a.
