STUDY AND EXPLORE CAO BANG'S NICKEL ORE FLOTATION CAPACITY

Abstract

This paper presents the research results of the exploration of Cao Bang
nickel ore flotation capacity with the original content of Ni = 1.18%,
Cu = 0.89%. Identified reasonable regimen: Crushing fineness 83.94% grain
level -0.074mm; R/L content = 30%; recruitment environment pH: 8; Active
drug Na2S: 400g/t; Butyl xantate: 350g/t; Pine oil foaming agent: 100g/t.
Experimental results obtained ore concentrate content Ni = 7.04%, Cu = 3.49%,
corresponding to the actual metal collecting Ni = 80.96%, Cu = 53.21%.
