DIRECT REDUCTION OF NICKEL BASIC CARBONATE

摘要

The object of the present Invention is the production of Nickel Metal substantially free of Sulphur by a New procedure that Saves at leastA Step or operation and which can easily be implemented without major technological changes.The Procedure refers to the treatment of Basic Nickel carbonate with hydrogen gas or any other gas, or solid Reducer LOW SULPHURAt high temperatures in a Furnace Floor, rotating, etc.The establishment of the Reduction Scheme is based on the Study of the physical - chemical properties of the basic Nickel carbonate and is staggered, soTo achieve the first Drying, calcination and finally after or simultaneously, reduction to metal.The Procedure refers to any type of Basic carbonate, but preferably a basic carbonate obtained after separate Nickel Cobalt by any meansAs the gas Hydrogen Sulphide
