Oxygen-enriched Top-blowing Submerged Lance Bath Smelting &Converting
Solved Problem

Oxygen-enriched top-blowing submerged lance bath smelting technology (TSL technology)  includes  ISA  process  and Ausmelt  process,  both  of which  use vertical cylindrical metallurgical furnace. Oxygen-enriched air is blown into bath through lances positioned at furnace top to complete chemical reaction. This technology is characterized with strong adaptability to different feeds, flexible operation and high smelting intensity, etc. The TSL furnace usually operates together with settling furnace. TOMINE has designed 9 smelters using TSL technology, with concentrate throughput over 5600kt/a.

Top-blowing converting technology, invented based on top-blowing smelting technology,   also   adopts   vertical   cylindrical    metallurgical   furnace. Oxygen-enriched  air  is  blown  into  bath  through  lances  positioned  at furnace top to enable reaction of matte and production of blister. This technology  is  featured  with  large  converting  intensity,  high  oxygen enrichment, small offgas volume and small footprint, etc. The company  has designed 2 smelters using top-blowing continuous converting technology.

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.
