· With the depleting reserves of highgrade iron ore in the world, froth flotation has become increasingly important to process intermediate and lowgrade iron ore in an attempt to meet the rapidly growing demand on the international market. In over half a century''s practice in the iron ore industry, froth flotation has been established as an efficient method to remove impurities from iron ore.

Iron ore concentrate is produced from the magnetite iron ore in the beneficiation process and is used for the production of pellets for blast furnaces and sinter. The concentrates are nontoxic, nonflammable and nonexplosive. The concentrate is shipped as a bulk commodity by rail using the opentop rolling stock and by sea.

Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of % pure copper called cathodes, which will ultimately be made into products for everyday most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different
WhatsApp Mining and processing of iron ore involves coarse crushing and screening. Iron ore is beneficiated by crushing and then separating the iron from the gangue minerals through screening. This is usually so efficient that lower grade ore can be treated especially when the magnetite is quite coarse. Common iron ore crushers are jaw crusher, cone crusher and fine jaw crusher.
