Reclamation operations are usually underway as soon as the coal has been removed from a mine site. The process includes restoring the land to its approximate original appearance by restoring topsoil and planting native grasses and ground covers. Recovery — The proportion or percentage of coal or ore mined from the original seam or deposit.
Ore sort 'waste' from the Volcanic unit is low grade ore and will be stockpiled for processing later in the mine life. Ore sorting pre-concentration increases the mill feed gold and silver grades by 32% and 31% respectively compared to run of mine (ROM) grades. Crushed ore is transported to the grinding circuit by an over land conveyor.

Grab sampling for underground gold mine grade control S.C. DOMINY Snowden Mining Industry Consultants Limited, Weybridge, England and University of Ballarat, Mount Helen, Australia Geologists in some underground gold mines collect grab samples from broken ore piles or trucks as a method of grade control. It is often known as muck sampling.
Mercury processing, preparation of the ore for use in various products. Mercury (Hg) has a unique combination of physical properties. Its low melting point (−38.87 °C [−38 °F]) and boiling point (356.9 °C [674 °F]), high specific gravity (13.5 grams per cubic centimetre), uniform volume expansion
during weathering or handling of the friable ore. The efficiency of the ferrochrome process is very much driven by the type and pre-conditioning of the feed materials. Processing fine feed material requires high operating temperatures and consequently
Some of the basic ore processing technologies (for friable ore) used in various Indian chrome ore processing plants (ref. figure-1) are as follows: (i) Manual screening cum washing of ROM ore by spray of water in 2 mm size screen followed by vigorous manual churning of screen under-size in a settling tank. The coarse chromite concentrates

The eventual aim of the block caving method is that the friable ore needs no blasting and continues to fracture and break up on its own, flowing down the drawbells to the extraction level, where it is removed from the ore chute mouths with loaders and sent off for processing.
For the most part they have exploited friable itabirite – material that requires little if any grinding; while compact itabirites have been less frequently exploited as they require grinding at a higher process cost. For West African type deposits, SRK's experience is that there is no guarantee of successfully developing a viable flowsheet.
Unlike other base metal ores, bauxite ore does not require complex extraction processing, because most of the mined bauxite is of an acceptable grade or can be improved (beneficiated) by a relatively simple but not inexpensive process of removing clay.
Friable Ore is the form of chrome ore with majority of particles measuring more than 10.00 millimeters. It is also in non concentrated form. Friable are less naturally occurring than fines as the ore is reduced to fine particles during beneficiation process.
