Ore Reserve Estimation Method
Actually, the total recovery in some instances may be more, since sorting may enable profitable mining of considerable tonnages of ore of too low-grade to be included as ore in the ore-reserve estimates. Another problem often met is the recalculation of tonnages and grades where the vein width is less than the practicable stoping width.

Flotation
The FLOTATION PROCESS is one of the commonest methods of extracting the valuable minerals from certain classes of ores, and it is generally more efficient as regards the recovery of the minerals than any other process applicable to the treatment of similar types of ores. The metallic contents of the minerals are recovered from the concentrates in a …

Nickel
Nickel is a silvery-white metal with a slight golden tinge that takes a high polish. It is one of only four elements that are ferromagnetic at or near room temperature; the others are iron, cobalt and gadolinium.Its Curie temperature is 355 °C (671 °F), meaning that bulk nickel is non-magnetic above this temperature. The unit cell of nickel is a face-centered cube with the lattice …

Copper extraction
The average grade of copper ores in the 21st century is below 0.6% copper, with a proportion of economic ore minerals (including copper) being less than 2% of the total volume of the ore rock. A key objective in the metallurgical treatment of any ore is the separation of ore minerals from gangue minerals within the rock.

Nickel Metal: It's Properties, History, Production & Uses
History . Baron Axel Fredrik Cronstedt first extracted pure nickel in 1751, but it was known to exist much earlier. Chinese documents from around 1500BC make reference to 'white copper' (baitong), which was very likely an alloy of nickel and silver.Fifteenth-century German miners, who believed they could extract copper from nickel ores in Saxony, referred to the …
