Side-Blown Bath Melting Technology For Nickel Matte Productior - Manufacturing, Other
Most of the existing laterite nickel mines in Indonesia use the RKEF process to produce about 10% ferronickel alloy. Main equipment: wet ore drying kiln, roasting reduction kiln, electric furnace. RE innovation oxygen-enriched side-blown smelting technology solution can produce 10-15% nickel matte. Main equipment include: wet ore drying kiln, roasting reduction kiln, oxygen-enriched side-blown smelting furnace. The designed annual processing capacity is 1 million tons of laterite nickel ore (wet ore)
The global nickel production areas are mainly distributed in Australia, Canada, the Philippines, Russia, Brazil, and Indonesia.
The global nickel production areas are mainly distributed in Australia, Canada, the Philippines, Russia, Brazil, and Indonesia. According to the USGS, the global reserve increase from 2015 to 2020 is approximately 17 million tons, and Indonesia increased production by 16.5 million tons. In terms of production, global nickel mine growth about 230,000 tons, Indonesia`s increase was 640,000 tons, accounting for 279% of the global increase.
- Replace electric furnace with oxygen-enrich side blown furnace, greatly reducing energy consumption and production costs.calculated based on production cost per processing tons of roasted sand, the oxygen-enriched side-blown furnace can save about 20USD compared with the traditional electric furnace process. Calculated by one production line of 1 million tons of Laterite nickel ore, our process can save about 11 million USD per year for a single line.
- No need for high-temperature sand transfer, avoiding the danger during transfer, reducing equipment investment and manpower requirements, and improving the operating environment.
- The process design is more reasonable, the flue gas from the oxygen-enriched side blown furnace is directly sent to the wet ore drying kiln as a drying heat source, reducing fuel consumption and improving energy utilization.
- The layout of the production line is more compact and reasonable, reducing land demand.
