Extraction of nickel from the laterite ores Hydrometallurgical process involves ammoniacal or sulfuric acid leaching followed by nickel precipitatation In the pyrometallurgical process the ore is dried and calcined in a rotary kiln and then smelted in an electric furnace with addition of carbon The grinding work index for preheated laterite was obtained about 35 lower than that of no preheated original ore Generally the experimental results showed that preheating treatment promoted in increasing the crushing strength of briquette and decreasing energy consumption for the grinding of laterite ore

Aug 21 32 Laterite Monument of laterite brickstones at Angadipuram Kerala India which commemorates where laterite was first described and discussed by Buchanan Hamilton in Laterite is a soil and rock type rich in iron and aluminium and is commonly considered to have formed in hot and wet tropical areasIron ore is the raw material used to make pig iron which is one of the main raw materials to make steel—98 of the mined iron ore is used to make steel Indeed it has been argued that iron ore is more integral to the global economy than any other commodity except perhaps oil
