Nickel Sulfide versus Laterite : the Hard Sustainability Challenge Remains
There are widespread nickel resources around the world, but divided principally between nickel sulfide or laterite (oxide) resources. Historically production has been dominated by sulfide ores but future production is increasing shifting to laterite ores. The principal reason for this historically is that sulfide ores are easier to process, through conventional mining, smelting and refining, co...
متن کاملX-Ray mapping and the mineralogy pattern of nickel laterite ore: Bavanat, Fars, Iran
According to the classification of the nickel laterite, this paper describes mineralogy test is to reveal where valuable elements are located in the ore, in which mineralogical form. The purpose of the sieving test was to study if some specific particle size contains most of the valuable metals. Based on its chemical composition nickel laterite is classified as a limonite type and the nickel an...
متن کاملDissolution of Nickel and Cobalt from Iron-Rich Laterite Ores Using Different Organic Acids
Due to the decreasing production of nickel and cobalt from sulfide sources, the Ni and Co extraction from the oxide ores (laterites) have become more prevalent. In this research work, the effects of calcination prior to leaching, acid concentration, percent solid, pH, and stirring speed on the nickel and cobalt recoveries from an iron-rich laterite ore sample were investigated using diffe...
متن کاملUnderstanding the agglomeration behavior of nickel laterite and gold ores using statistical design of experiments
The drum agglomeration of nickel laterite and gold ores has been optimized through the design of experiments (DOE) using a Taguchi L16 (45) orthogonal array to determine the optimum conditions for maximizing average agglomerate size and minimizing the amount of fines. The effects of controllable operating factors including moisture content (nickel laterite ore: 34-37%; gold ore: 7-10%), retenti...
متن کاملSynthesis and Characterization of Nickel and Zinc Sulfide Ethylenediamine Complexes
In the present work, nickel and zinc sulfides ethylendiamine (N2H4C2H4) complexes were prepared in an autoclave at 180 C for 12 h. Transmission electron microscope (TEM) and X-ray powder diffraction were used to study the morphology of the two samples. The infrared absorption spectra were obtained and discussed in the range (200-4000 cm). New bands appeared at about 238,240 and 297 cm assigned ...
