Recovery % Represents the ratio of the weight of metal or mineral value recovered in the concentrate to 100% of the same constituent in the heads or feed to the process, expressed as a percentage. It may be calculated in several different ways, depending on the data available. By assays f, c and t only: R = 100 c(f — t)/f (c — t) = recovery %

Process Mineralogy Mineral Processing & Metallurgy

Hematite is an iron mineral present in varying types, sizes and shapes from 10-50 microns to 300-900 microns grains of acicular, lath shaped, equant, crystalline to irregular shapes. These minerals may exhibit microbanding, microplaty, and reticulate textures.

Iron | Minerals Education Coalition

Iron is the third most common element making up the Earth. Iron is one of the three naturally magnetic elements; the others are cobalt and nickel. Iron is the most magnetic of the three. The principle ores of iron are hematite (70% iron) and magnetite (72% iron). Taconite is a low-grade iron ore, containing up to 30% magnetite and hematite.

Iron Ore Recovery from Low Grade by using Advance Methods

Iron Ore Recovery from Low Grade by using Advance Methods Thus, beneficiating the low-grade iron ores to remove the gangue minerals and enhancing their grade is an attractive proposition today. Among the known iron deposits in Karnataka, many are of low-grade which require beneficiation to produce an acceptable feed for steel making plants.

Ore Dilution & Recovery in Mining

Recovery and dilution usually are interrelated; with some methods of stoping a high recovery involves contamination of the ore from the walls or capping, and often clean ore can be obtained only by leaving some ore in the mine. In open-stope mines the greatest loss of ore is that tied up in pillars left for support of the back or hanging wall.
