The metal ions binding onto the extracellular surface of the algae due to polymeric material nature of the cell walls is another mechanism of metal tolerance in algae and microbes. Many cyanobacteria and algae secrete copious amounts of mucilaginous2 materials of different types; primarily composed of polysaccharides. This material has a
· The mining process is responsible for much of the energy we use and products we consume. Mining has been a vital part of American economy and the stages of the mining process have had little fluctuation. However, the process of mining for ore is intrie and requires meticulous work procedures to be efficient and effective.

· Underhand Stoping Mining Method. The method of underhand stoping in which the ore is drawn to the level above (B, Fig. .1), is called Cornish stoping. It finds appliion only when it is necessary to mine a lens of good ore below a level and it is not practicable or financially possible to do the necessary development to come up from underneath.

These mines will bring in ~Rs. 5000 crore (US million) in annual revenue for the state and employment opportunities for locals. In February 2021, CIL signed a contract with Belaz, a Belarusbased mining equipment manufacturer, for procurement of dumpers with an investment amount worth Rs. 2,900 crore (US million).
The reason for metal accounting along the mining value chain A diagrammatic representation of the value chain for a typical base metal operation producing copper and cobalt is shown in Figure 1 (Macfarlane, 2011). The reasons for adopting an end–toend approach to metal accounting along the value chain can be summarized as follows:

Underground hardrock mining refers to various underground mining techniques used to excavate "hard" minerals, usually those containing metals, such as ore containing gold, silver, iron, copper, zinc, nickel, tin, and also involves the same techniques used to excavate ores of gems, such as diamonds and rubies. Softrock mining refers to the excavation of softer minerals, such as salt ...

Native metal A metal occurring in nature in pure form, uncombined with other elements. Net profit interest A portion of the profit remaining after all charges, including taxes and bookkeeping charges, such as depreciation, have been deducted. Net smelter return A share of the net revenues generated from the sale of metal produced by a mine.
Primary Mining Method Sequential grid down dip. Information. To deal with ground pressures, a Vshaped mining sequence is utilized. The main advantages of the sequential down dip method are the very low energy release rates, which make backfilling unnecessary, and the allowance for the physical separation of rock transport from men and materials.
Placer mining Placer mining is used when the metal of interest is associated with sediment in a stream bed or floodplain. Bulldozers, dredges, or hydraulic jets of water (a process called 'hydraulic mining') are used to extract the ore. Placer mining is

· Scrapers are sometimes used in special situations. Large bucketwheel excavators of the kind used in European coal mines have not been applied to metal mining, because this equipment is best adapted to softer bedded, relatively flatlying strata. Many factors govern the size and shape of an open pit. These must be properly understood and used in the planning of any open pit operation. The ...
