Manufacture of iron. Many reactions take place as the gases make their way upwards. Coke reacts with oxygen in the blast to form carbon monoxide, a reducing agent: If oil or natural gas is used, the hydrocarbons produce a second reducing agent, hydrogen: Figure 3 A .

In adopting a best practice approach to waste rock management for their iron ore mine in Western Australia's Pilbara region, Roy Hill developed an AMD Management System that is comprised of both an AMDMP and an AMDOM that are connected through adaptive management processes.

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) opencast mining for ...
Waste rock can be processed to a desired gradation by crushing and sizing, like any other source of aggregate. The hardness of the waste rock is determined by the rock type. For example, iron ores are often found in hard igneous or metamorphic rock formations, so waste rock from iron or taconite ore processing is usually hard and dense.
The Business Insider has reported that an Australian company is harvesting blast furnace waste and converting it into a new product to make cement in China, where 60% of the world's iron waste is found. The new technology is called Dry Slag Granulation (DSG) and it reduces water use and cuts greenhouse gas emissions.
Steel makes up the largest category of metals in the municipal solid waste (MSW) and industrial waste streams. Steel since ages has been a recycled material throughout the world. Solid wastes in steel plants are essential byproducts generated during various processing steps involved in the production of iron and steel.
Waste from gold mining. This is a rough estimate. The gold used to make a single gold ring of grams produces around 26 tons of mine waste. Consequently, the annual production of 2,700 tons of gold produces about billion tons of waste. Report: Dirty Metals
One layer is a waste containing iron and silica compounds and is discarded as slag slagByproduct left after a desired metal is thermally separated from its raw ore.. Approximately 75 percent of the copper concentrate ends up as slag. The other layer, called "matte copper," consists of copper, iron sulfide and other metals.
A blast furnace is charged with iron ore, charcoal or coke (coke is charcoal made from coal) and limestone (CaCO 3 ). Huge quantities of air blast in at the bottom of the furnace, and the calcium in the limestone combines with the silicates to form slag.
