Description: This project is for support of cooperative research by Dr. Renato Bautista of the Department of Chemical and Metallurgical Engineering at the University of Nevada, Reno and Dr. C.K. Gupta of the Extractive Metallurgy Division of the Bhabha Atomic Research center (BARC) in Bombay, India. The project is to characterize the application of cupric chloride leaching to complex nickeliferous sulfide ores where the nickel is mainly present in the minerals millerite (NiS) and pentlandite (NiFeS). Experimental work will be done at BARC and mathematical modeling will be developed by the U. of Nevada team. The effect of different parameters on the rate of leaching of the nickel sulfides will be examined. The rate of dissolution of both millerite and pentlandite will be developed from the experimental data, including their rate constants and activation energies. The mathematical model will cover the leaching reactions and the simultaneous reactions in the solution phase. The information derived from the experimental work and the model will be applied to an indigenous nickel-copper sulfide concentrate. Scope: the project brings together two experienced scientists from India and the U.S. to work on a problem that has significant importance to the material processing industry in the U.S. and India. This collaboration meets the objective of the U.S.-India Cooperative Program.

描述：该项目是为了支持雷诺内华达大学化学和冶金工程系的Renato Bautista博士和印度孟买Bhabha原子研究中心(BARC)提取冶金部门的C.K.Gupta博士的合作研究。该项目旨在描述氯化铜浸出在复杂的含镍硫化物矿石中的应用，这些矿石中的镍主要存在于矿物Millerite(NiS)和镍黄铁矿(NiFeS)中。实验工作将在BARC进行，数学模型将由内华达大学的团队开发。考察了不同工艺参数对硫化镍浸出率的影响。根据实验数据，包括它们的速率常数和活化能，可以求出镁橄榄石和镍黄铁矿的溶解速度。数学模型将涵盖溶液相中的浸出反应和同时反应。从实验工作和模型中获得的信息将应用于本土的镍铜硫化物精矿。范围：该项目汇集了来自印度和美国的两位经验丰富的科学家，致力于解决对美国和印度的材料加工业具有重要意义的问题。这种合作符合美印合作计划的目标。
