Froth Flotation Principles

Lead-Zinc-Gold-Silver Flotation: This Colorado mill, treating a complex lead-zinc ore carrying gold and silver values, uses a Mineral Jig and a "Sub-A" Unit Cell in the closed grinding circuit. The jig recovers coarse and fine heavy minerals (as soon as free) which are difficult to float due to size and specific gravity.

Iron Ore Processing: From Extraction to Manufacturing

The final stage in iron ore processing is ironmaking, where the iron ore is transformed into molten iron through a process called reduction. The most common method of ironmaking is the blast furnace route. In a blast furnace, iron ore, coke (carbon), and fluxes (limestone or dolomite) are loaded into the furnace from the top.
