Magnetite – Karawara Minerals
With magnetite, producers can use basic physics to separate the valuable from the worthless while reducing harmful and even toxic by-products, through Dense Media Separation (DMS). DMS is used commonly in mineral processing to elevate the concentration of specific minerals and reject waste at early stages of mineral processing.
Magnetic Separation
The separation is between economic ore constituents, noneconomic contaminants and gangue. Magnetite and ilmenite can be separated from its nonmagnetic RFM of host rock as valuable product or as contaminants. The technique is widely used in beneficiation of beach sand. All minerals will have one of the three magnetic properties.
