Chromite tailings wear filter cloth faster than gold or copper tailings. Four dewatering routes compared on cake moisture, cost and wear life.

Dense medium separation handles coarse chromite; spirals take the fines. The cut point is set by liberation size, Cr:Fe target and the share below 1 mm.

A gold wash plant catches free metal. A chrome wash plant has to lift the Cr:Fe ratio and drop silica. Same building, different separation logic.

Metallurgical, refractory and chemical chromite each set a different Cr:Fe and silica limit. The beneficiation route has to end where the buyer spec begins.

Only 11% of Kazakhstan tailings and waste dumps are processed. What the 2026 tax cut changes, and the three process barriers that still stop projects.

Tungsten is mined three ways, and the deposit type decides which. Skarn, quartz-vein and porphyry orebodies set the method and the flowsheet.

A copper tungsten ore has to make two saleable concentrates from one feed. Here is how the flowsheet balances copper recovery against scheelite grade.

Fine slimes coat mineral surfaces, waste reagents and drag down spodumene recovery. Removing them first is cheaper than fixing a flotation that fails.
