Nov 26, 2020· According to managing director Justin Werner, the deal has total valued US$490 million. The Angel nickel project comprises four rotary kiln electric furnace lines and a captive 380 megawatts power station, which is currently under construction within the Indonesia Weda Bay Industrial Park (IWIP) on Halmahera Island, in North Maluku province
The result is a smelter utilising onekilnand onefurnacewhich treats 240 t/h of calcine and produces 36,000 t/y ofNicontained in ferronickel from ore containing 2 %Ni. Such a plant, with the minimum number of large operating units, would achieve minimum capital and operating costs per tonne of ferronickel production
Two-thirds of the global nickel output can be attributed to the rotary kiln-electric furnace process. Due to the high contents of MgO and SiO 2 in laterite, a high temperature (∼1600 °C) and corresponding energy (approximately 14 GJ/t-ferronickel) are …
We have rotary kiln electric furnace nickel,Ore after drying in laterite nickel ore by rotary kiln in rotary kiln is heated to 800 DEG C after removal of the ore surface water and crystal water and reducing ore of iron nickel and cobalt oxide into the smelting furnace Compared with laterite kiln process and blast furnace or electric furnace process has the following advantages

The rotary kiln and electric furnace process has long been the most commonly employed method of recovering nickel from saprolitic laterite ores. Production improvements have been achieved over the years by the adoption of “shielded arc” smelting and the installation of water-cooled copper cooling elements in the furnace sidewalls
Rotary Kiln Electric FurnaceProcess. Lateritenickel rotary kilnis one of the key equipment in the lateritenickelorerotary kilnsmelting after drying in lateritenickelore byrotary kiln, inrotary kilnis heated to 800 DEG C after removal of the ore surface water and crystal water, and reducing ore of iron,nickel, and cobalt oxide, into
After the upgrading process, the dried ore is then blended with a reductant agent (locally bought coal) and calcined in two rotary kilns. Calcined ore is then transferred to two 75 MW electric furnaces where ferronickel is tapped at around 1,460° C. The crude metal is transported to the refinery where impurities are removed
