The red mud waste dries to a very fine, powdery solid and contains significant amounts of iron, aluminum, calcium and sodium. The types and concentrations of minerals present in the muds depend on the composition of the ore and processing conditions. In some plants, red muds are further processed to produce aluminum oxides.

Sep 01, 2008· The iron ore is predominantly mined by opencast mining throughout the country. The solid material generated in large quantities by iron ore extraction is the material that overlies the ore body and the processed tailings . These wastes contain minerals associated with the ore body and host rock, mainly the laterite, and sometimes the clays.
Mining Waste Products. The types of waste materials generated are dependant upon the type of mining activity. Around the Fal Estuary there have been effectively three main types of mining activity: (1) the recovery of cassiterite from the river sediments (so called tin streaming or placer mining); (2) the underground and opencast mining for metal (hard rock mining); and (3) .

Jul 18, 2013· Traditionally, iron ore has been reduced with coke in a blast furnace and the hot metal product of the blast furnace containing carbon, manganese, silicon, sulphur and phosphorous, was subsequently refined in a steelmaking furnace. During ironmaking as well as during steelmaking, significant amounts of slag are produced.
The end products are usually molten metal and slag phases tapped from the bottom, and waste gases (flue gas) exiting from the top of the furnace. The downward flow of the ore along with the flux in contact with an upflow of hot, carbon monoxide-rich combustion gases is a countercurrent exchange and chemical reaction process.

The ratio between waste rock and ore production is called the stripping ratio. For example, a stripping ratio of 2:1 means that 2 tonnes of waste rock needs to be mined to mine 1 tonne of ore. Generally, an open pit mine has a higher stripping ratio than an underground mine. Waste rock is often stored close to the mine to minimize transports.
Acid rock drainage from waste rock. Although the character of waste rock varies with the type of ore, many waste rocks contain sulfide minerals associated with metals, such as lead, zinc, copper, silver, or cadmium. An important sulfide mineral common in waste rock is pyrite, iron sulfide.

Open pit mining has several stages of waste. First, to access the actual seams or veins of ore, the top layers of rock, or overburden, must be removed. Once the overburden has been removed, the seams can be extracted. When extracting the seams, the additional waste rock will be removed to get to the actual ore, called gangue.

These wastes include iron ore fines, pollution control dust, coke breeze, water treatment plant sludge, and flux. Sintering plants help reduce solid waste by combusting waste products and capturing trace iron present in the mixture. Sintering plants are not used at all steel production facilities.

The total amount of hard coal and ore mining and processing waste laying in dumps at the end of 2000 was 1253.5 Mt that was 63.4% of total amount of all wastes disposed throughout the country. Of that, hard coal mining waste comprised 53.3% and metal ore (copper) mining and processing, 46.7%.
Extracting iron from iron ore using a Blast Furnace. The common ores of iron are both iron oxides, and these can be reduced to iron by heating them with carbon in the form of coke. Coke is produced by heating coal in the absence of air. Coke is cheap and provides both the reducing agent for the reaction and also the heat source.
