Re-Processing Gold Tailings in South Africa

The tailings from the re-processing plant will be re-deposited in a new area far from urbanization, allowing for the rehabilitation of the real estate currently occupied by these historic tailings. The first step in the process involves a mild-regrind and mild acid leach of the tailings (pH 2.5 to 3.0) to dissolve up to 40% of the uranium.

Metal Oxides In Soils: The Effects Of Hematite And Magnetite

Magnetite is a form of iron oxide, Fe 3 O 4, which possesses uniquely iron in both the Fe 2+ and Fe 3+ oxidation states. Bearing the form of an inverse spinel, it's magnetic properties are highly valued. Addition of magnetite to soil is advantageous as it can later be removed easily by using magnets. It can occur naturally in soil, or be added as a soil treatment agent.
