2021-8-14 The Tulaergen magmatic Ni-Cu sulfide ore deposit is located along the southern margin of the Central Asian Orogenic Belt in northwestern China. This deposit is hosted by a small mafic–ultramafic complex composed of a Late Carboniferous (~ 301 Ma) gabbroic member at the margin and a younger ultramafic dyke in the center. Net-textured and semi-massive sulfides are mainly concentrated in the ...

2020-5-6 Interspinifex ores and their significance. The textures of magmatic sulfide ores contain important clues to the physical processes of emplacement and migration of Fe–Ni–Cu–Co-bearing sulfide ore magmas (Barnes et al. 2017, 2018).Textural studies have revealed a remarkable ability of sulfide liquid pools to partially melt solid substrate rocks and displace silicate melt, forming ...

: EXTRACTING METALS FROM SULFIDE ORES

Many approaches were pursued to solve the "sulfide problem" at Broken Hill before selective flotation was developed. The successful technology involves first crushing the ore, typically to a particle size of about 5 to 50 micrometers, to liberate separate grains of the various valuable minerals and worthless gangue components.Then the particles are pulped with water, and the surface of the ...

2017-3-4 The ore has a 5 to 10 percent sulfide content, so I expect about 10 to 20 pounds of sulfide concentrate. Dealing with 10 to 20 pounds is a lot easier than 200 pounds. There will be some loss of values in this operation - but I accept this because although the method is less than optimal, it's the best I can put together.
