Bushveld chromite is conveniently milled to recover a fine concentrate by gravity and elutriation techniques. However, ferrochrome furnaces need a porous charge so lumpy ore and chips must also be recovered by dense medium separation to mix with the fines.
Chromium is used in metallurgy to impart corrosion resistance and a shiny finish; as dyes and paints, its salts colour glass an emerald green and it is used to produce synthetic rubies; as a catalyst in dyeing and in the tanning of leather; to make molds for the firing of bricks. Chromium (IV) oxide (CrO 2) is used to manufacture magnetic tape.

Chromium is used in many industrial applications, but it poses a threat to local environment. The effluents and solid wastes from the mining, chromeplating, leathertanning, and dyemanufacturing industries are high in chromium concentration and identified as a major health hazard because of pollution to the environment.

The Copper Age | The Bronze Age | The Middle Ages and Later | Mining. Copper minerals and ores are found in both igneous and sedimentary rocks. Mining of copper ores is carried out using one of two methods. Underground mining is achieved by sinking shafts to the appropriate levels and then driving horizontal tunnels, called adits, to reach the ore.

Overview. Chromium is a steel gray, lustrous, hard metal extracted from chromite ores. In 2011, production of chromium was estimated at 160,000 metric tons, coming almost entirely from recycling stainless steel scraps. In addition, the imported 430,000 metric tons of chromium, primarily from South Africa, Kazakhstan, Russia and China.
Chromium is traded on the world market in the form of ferrochromium, an ironchromium alloy. Text prepared by Kropschot and Jeff Doebrich; designed by Glover. The USGS Mineral Resources Program is the sole Federal provider of research and information on chromium and .
Mar 08, 2005· Generally, these are ironbase alloys that contain high amounts of chromium (greater than 18 percent) and carbon (greater than 3 percent). These elements form hard carbides (chromium carbides) that resist abrasion. The deposits frequently checkcrack about every 1/2 in., which helps relieve stress from welding.
