However, the preferred starting material is milled high-carbon ferrochrome that is leached in recycled anolyte and make-up H 2 SO 4. A simplified flow sheet showing the essential steps in the process is given in Figure 3-2. The 20-mesh ferrochrome (67 percent chromium) is leached at about 90 °C in roughly 3-metric-ton batches without agitation.

Froth flotation is an important concentration process. This process can be used to separate any two different particles and operated by the surface chemistry of the particles. In flotation, bubbles are introduced into a pulp and the bubbles rise through the pulp. In the process, hydrophobic particles become bound to the surface of the bubbles.
