Upgrading nickel in laterite ores by flotation -

01/06/2018  Flotation has not been successful to recover nickel from laterite ores because of the fine-grain and low grade nickel. Nickel laterite deposits are generally divided into limonite (oxide), nontronite (clay) and saprolite (silicate) zones. A systematic study was conducted on the ore samples sourced from these three categories to see the effect of different mineralogies on the flotation behaviour of laterite

Exploration of a novel depressant polyepoxysuccinic

Nickel sulfide minerals are a primary nickel source for industrial beneficiation, in which froth flotation is the main method employed (Liu et al., 2018a; Yu et al., 2019; Peng et al., 2020). The rapid depletion of high-grade ores has created a critical demand for processing low-grade nickel sulfide ores containing high quantities of various clay gangue minerals ( Wang et al., 2015 ).
