laterite is formed when heavy tropical rainfall results in intense weathering of rock and soil. the chemistry of weathering silicarich rocks sees the relatively mobile elements such as calcium sodium potassium and magnesium being washed away while the immobile metals including aluminium iron titanium and zirconium remain.

blast furnaces were used as a stop gap measure in china when iron ore supplies either became too expensive or dwindled however proved to be uneconomichence you do not see any bfs being built in china for treating nickel laterite ores.
laterite nickel ore calcination process. introduction of laterite nickel ore calcination process: laterite nickel ore resources is the sulfide nickel ore rock goes through weatheringleachingdeposition to form surface weathering crust deposit.
the separation of the alumina from the impurities in the bauxite ore is usually accomplished by the bayer process. in this process the ground bauxite is leached with caustic soda naoh to produce soluble sodium aluminate naalo2 leaving the impurities in the insoluble residue.
from sulfide ores.because the conversion of nickel sulfide directly to metal would require an extremely high temperature in excess of 1600 °c [2910 °f] the removal of sulfur at this stage of the converting process is controlled in order to produce the 7075 percent nickel matte which has a lower melting point.
