Iron Ore Beneficiation | SRK News - SRK Consulting

Ores can often respond to gravity and/or magnetic separation. However, due to the presence of lower-iron content, iron minerals such as goethite, mass yields and recoveries to high grade concentrates can be low. Trade-offs are then required between recovery and product quality (iron grade and penalty element content).
