The water was used for a variety of purposes, including removing overburden and rock debris, called hydraulic mining, as well as washing comminuted, or crushed, ores and driving simple machinery. The Romans used hydraulic mining methods on a large scale to prospect for the veins of ore, especially a now obsolete form of mining known as hushing.

Sintering. Iron ore sintering consists of heating a layer of fines until partial melting occurs and individual ore particles fuse together. For this purpose, a traveling-grate machine is used, and the burning of fine coke (known as coke breeze) within the ore generates the necessary heat.

As a verb, it refers to selective mining of the best ore in a deposit. High-grader - One who steals rich ore, especially gold, from a mine. Hoist - The machine used for raising and lowering the cage or other conveyance in a shaft. Holding company - A corporation engaged principally in holding a controlling interest in one or more other companies.

Surface mining equipment is similar to construction equipment (e.g., scrapers, bulldozers, drills, shovels, front-end loaders, trucks, cranes, draglines). ... Flocculation technologies are used in the iron-ore industry to flocculate and recover iron oxide and in the clay industry to flocculate the quartz and reject grit.

As the industrial revolution developed, so did the iron industry. A set of innovations, from different materials to new techniques, allowed iron production to expand greatly. In 1709, Darby became the first man to smelt iron with coke (which is made from heating coal). Although this was a key date, the impact was limited — as the iron was ...

Lead processing - Mining, Concentrating, Refining: Once the ore is removed from veins (narrow channels) or lodes (roughly spherical deposits) in the Earth, usually at depths of about 60 metres, the ore is treated at concentrating mills.
