Flash Smelting Technology is featured with quick reaction speed, high reaction temperature, strong smelting intensity, high production efficiency, and high level of automation and good environmental performance; and it is also suitable for large-scale production system. The company has abundant engineering experience in commercializing this technology and has independently designed multiple flash smelting systems. Meanwhile, the company has developed a synthetic furnace incorporating flash furnace and electric furnace, making composite furnace and electro-thermal slag cleaning furnace be directly connected, as do their baths. The technology enables the furnace to directly produced is card slag, thus achieving low energy consumption and high direct recovery.
Flash Converting Furnace adopts similar furnace type with flash smelting furnace. Copper matte is granulated, ground and dried before being fed into converting furnace through the nozzle of reaction shaft to produce blister as a result of reaction. The world’s largest flash smelting + flash converting system engineered by the company was built and commissioned in 2013 in Fangchenggang, Guangxi province, China. Meanwhile, the company has also successfully commercialized the suspension converting technology one example is for Sanmenxia Au&Cu Smelter whose suspension converter is a wholly proprietary metallurgical furnace type with blister output of 300kt/a
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.
TOMINE Oxygen-enriched side-blowing bath smelting technology adopts a fixed horizontal furnace with concentrate directly into furnace
TOMINE BCC furnace is also of horizontal type with oxygen-enriched air blowing into furnace via lances positioned at the furnace
