Combined processing of products with high content of silicate nickel

Abstract

The presence of nickel in sulfide copper-nickel ores, isomorphically bound to some silicate minerals, sometimes predetermines the possible enrichment results of such ores. The recovery of silicate nickel during flotation is low, and a significant part of it is lost in the tailings. According to M.N. Godlevsky, silicates of copper-nickel ores containing nickel are easily decomposed by acids. In this connection, a combined method was tested for processing products with relatively high silicate nickel content.
