A watermill or water mill is a mill that uses hydropower. It is a structure that uses a water wheel or water turbine to drive a mechanical process such as milling (grinding), rolling, or hammering .

Tailings produced from the milling of sulfide ores — primarily copper, lead, and zinc ores — may have concentrations of pyrite that are greater than those common in waste rock. Also, because tailings are composed of small mineral particles the size of fine sand and smaller, they can react with air and water more readily than waste rocks.

Extraction processes include dressing (picking, sorting, washing of ores), milling (crushing, grinding, etc.) and beneficiation (processing to improve purity/quality). Wastewater is generated during the mining process from groundwater produced during ore extraction, from water used by operators for equipment cooling and dust control, and from ...

Other factors include the gold concentration of the ore, the mineralogy and hardness of the ore, the mill's capacity, and the next planned step in the beneficiation of the ore.From the cone crusher, ore is fed to the grinding circuit where milling continues in the presence of water.

A backshot wheel (also called pitchback) is a variety of overshot wheel where the water is introduced just before the summit of the wheel. In many situations it has the advantage that the bottom of the wheel is moving in the same direction as the water in the tail race which makes it more efficient.

Considering the actual period of time the hazards from uranium mining and milling wastes persist, these regulations are of course only a compromise, but they are a first step, at least. ... Water covers for uranium mill tailings dams are ...

Without mineralogy, estimating the optimum Grind Size for Gold Ore Sample is most conveniently made by Laboratory Testing and the agitation leaching method, and it will be necessary to make up 3 or 4 bottle charges in order to have enough ore* for the subsequent screen analysis.

A watermill is an engine that uses a water wheel or turbine to drive a mechanical process such as flour or lumber production, or metal shaping (rolling, grinding or wire drawing). A watermill that only generates electricity is more usually called a hydroelectric plant .
