Underground Mining. Underground mining techniques include the digging of deep tunnels into rock near where coal or copper is located. Tunnels are constructed so miners can get the ores and load them into vehicles hence long steel bolts are erected to prevent the underground tunnels from collapsing.
Chromite is important because it is the only economic ore of chromium, an essential element for a wide variety of metal, chemical, and manufactured products. Many other minerals contain chromium, but none of them are found in deposits that can be economically mined to produce chromium.

Now is a situation where processing engineers can programme recovery of values from old tailings, mill rejects, marginal, submarginal and lean ores and over burden, which till today have been left over for want of technology, can be projected and processed as a usable source of minerals.
conventional uranium ore deposits are limited and lean in tenor. The indigenous supply of uranium to the power reactors of the country is met mainly ... yellow cake product from lowgrade uranium ores (U 3 O 8 <%) is quite challenging. The different process options generally
"Lessons Learned from the Copper Industry Applied to Gold Extraction" ... –"Lean Production" ... •Improvement in ore quality (grade) to process •Implementation of a new technology •Other improvements –Safety, health environmental –Sustainable development
It is lowgrade that magnetite iron mine in the superlean magnetite iron, and if we grind the raw ore and magnetic separate after primary crushing, the cost of beneficiation will be increased. So, the optimization way of processing superlean magnetite iron is most necessary.
Cerro Matoso has had its mined grades halved as it shifts from processing highgrade ore mined from the pit to lean ore, which has been stockpiled from previous mining operations, resulting in a significant increase in operating costs.

Metallurgy chemical kiln is mainly used for magnetized roasting of lean iron ore, and oxidizing roasting of chrome ore and nickel ore, etc. . When used in chemical industry, it is mainly used for roasting chrome ores.
Indian Iron Ore Scenario : Low Grade Iron Ore Beneficiation. Wide reserves of iron ore is found in India which is the basic raw material for iron and ... ores, beneficiation of low grade .
Title: Development of technology for beneficiation and agglomeration of low grade iron ores and slimes Use: Utilization of low grade iron ores for application in iron and steel making Slime (a waste from current industrial practice) treatment also entails waste utilization apart from producing raw
consider exploitation and utilization of low/lean grade ores. The accumulation of low grade lumps and fines, have increased with the increase in the production of iron ore. By adopting, simple processes like washing/scrubbing, it was not possible to upgrade these ores suitable for sinter or pellet ...

low cost, suitability for different mines and lean grade ores and environmental acceptability. In situ leaching Microbial in situ leaching (or solution mining) is a unique method of metal extraction from run
The runofmine lean grade copper ores were stacked in waste dumps over 100m in height and leached using acidic solutions for economic copper extraction at the Bingham mines of Kennecott Copper Company during the late 1950s and early
is often used to treat lean and complex ores, especially lowgrade ores, waste rocks tailings (Van der merwe and Kasaini, 2011; Ekenes and Caro, 2013; Haghighi et al., 2013) and results in the increase of metal recoveries and the reduction of air pollution. With the gradual depletion of highgrade
That raw ore including high phosphorus, high silicon, and low iron lean manganese carbonate, 20% manganese ore is the main manganese ore, apatite is the main harmful element, quartz, and clay is the main gangue minerals.
