As one of leaders of nsequences of extracting nickel industry, SBM always seeks innovation & excellence.
Said salt solution is forced at the rate of 0.5-1.0 ml/min. Note here that reaction mix is subjected to microwave radiation at frequency of 7.5-10.5 GHz. Said process is conducted at 20-30°C. Nickel salt solution is forced via powder of reduced iron repeatedly at simultaneous microwave radiation effects. EFFECT: higher degree of nickel extraction.

Nickel: smelting; Extraction and purification; Nickel is recovered through extractive metallurgy: it is extracted from its ores by conventional roasting and reduction processes that yield a metal of greater than 75% purity. In many stainless steel applications, 75% pure nickel can be used without further purification, depending on the composition of the impurities.

Leaching is the most widely used process for extraction of nickel metal from lateritic ores. In this study, nickel extraction from Manisa-Gördes region laterites by hydrochloric acid leaching is aimed. The mineralogical analysis of sample showed that hematite, goethite, dolomite, quartz and smectite are the main minerals in the ore.

May 05, 2020· 1. Introduction. Nickel is an important strategic metal produced at over 2 million tonnes annually [].Approximately 60% of all Ni is consumed in the production of stainless steel [2,3].Currently, Ni is primarily extracted from two types of ores: laterites and sulfides [,,, ].Although sulfide ores account for a smaller fraction of global Ni reserves, approximately 60% of global Ni production
