	Mineral Processing Wastes - Material Description
		Mineral processing wastes are referred to in the Resource Conservation and Recovery Act (RCRA) as wastes that are generated during the extraction and beneficiation of ores and minerals.
		Mineral processing wastes are available from mining and mineral processing operations, most of which are located near the mine source and operated by mining companies.
		The material properties of the various categories of mineral processing wastes are influenced by the characteristics of the parent rock, the mining and processing methods used, and the methods of handling and/or disposing of the mineral by-product.

	Mineral processing - Wikipedia, the free encyclopedia
		Mineral processing, otherwise known as mineral dressing, is the practice of beneficiating valuable minerals from their ores.
		Mineral processing involves manipulating particle size by crushing and grinding the ore. Combined with particle size classification unit operations, this area is often termed comminution.
		The ore is generally piled on heaps, and this process is part of the heap leaching processing method.

	Florida Institute of Phosphate Research - Mining and Mineral Processing (Beneficiation)
		FIPR's research in the areas of mining and beneficiation (mineral processing) concentrates on issues pertaining to the mining of phosphate rock and beneficiation of phosphate ore (matrix), which separates the valuable phosphate rock from waste clay and sand.
		Processing phosphate rock is the separation of phosphate from the mix of sand, clay and phosphate that makes up the matrix layer.
		Another research focus in the beneficiation area is to streamline the flotation process and reduce the number of reagents (chemicals) used to separate the sand and clay from the phosphate rock after it is mined.

	Specialty Chemicals - Chevron Phillips Chemical Company LLC
		In ore beneficiation, flotation is a process in which valuable minerals are separated from worthless material or other valuable minerals by inducing them to gather in and on the surface of a froth layer.
		The air bubble and mineral particle rise through the pulp to the surface of the froth or foam that is present on the flotation cell.
		The mineral is physically separated from the remaining pulp material and is removed for further processing.

	Mineral Processing Operator
		Mineral processing operators ensure that the plants where these ores are processed, run smoothly.
		Mineral processing operators, in consultation with plant metallurgists, make sure that the cycle occurs under the correct conditions, so that the rate of production, along with quality is maintained.
		Throughout the production cycle (where mineral bearing ore is crushed, milled, floated, thickened and leached and in some cases roasted and/or smelted), a mineral processing operator will monitor such factors as temperature, rate of oxygen flow, density and the rate of reaction.

	Mineral Processing Wastes - User Guidelines - Asphalt Concrete
		The current use of mineral processing wastes as aggregate in hot mix asphalt is not a common practice, due in great part to the relatively remote location of many sources of these wastes.
