The increasing world nickel demand coupled with depleting saprolite reserves throughout the globe requires that metal extraction be extended to the entire laterite ore body. To improve process throughput, the sedimentation behaviour of blended limonite-saprolite ore slurries is modified in gravity thickeners using ionic polymers. Based on 2 factorial design, ionic type, …

Lateritic soil sequences are formed from the weathering of rocks in circumstances conducive to leaching and oxidation; limonite is formed higher up in the sequence, with saprolite lower in the orebody. Indonesian nickel ore grades for limonite are generally in the range of 0.8% to 1.5%; for saprolite they may exceed 1.8%.

Di Indonesia, nikel kadar tinggi atau saprolite lebih mudah dijual, karena smelter untuk mengolah nikel tersebut sudah tersedia. Sedangkan nikel kadar rendah atau limonite masih jarang terserap. Tak heran jika potensi saprolite terus berkurang di Indonesia, hanya sekitar 930 juta ton, seperempat dari limonite yang mencapai 3,6 miliar ton.
