Gold Concentrators Oro Industries The Martin

OUR CLAIM: The MultiHelix Spiral is hands down the most efficient gold concentrator available in the industry. It has a proven track record with a recovery rate of 99% of all free gold. It is a commercial duty, gravity concentrator for both alluvial and fine milled hard rock ores and has the highest concentration ratio AND highest recovery rate of any gravity concentrator on the market

Silica and Iron Recovery from a Residue of Iron Ore

A study of silica and iron recovery from the iron ore concentration tailing is presented. The residue is composed of 40.1% Fe, 33.4% SiO2, 8.31% Al2O3, 0.08% P, and 0.34% MnO. The developed process of silica and iron recovery consisted of size classification, magnetic separation, and removal of impurities by leaching. A concentration of SiO2 from 33.4% to 67.0%, with 60.0% of mass reduction
