an existing iron ore/taconite processing facility. RESULTS A simple comparison of capital and operating costs alone shows: • Underground mining exceeds the cost of surface mining unless the waste to ore (stripping) ratio for surface mining is about 6:1 or greater. • Of the two underground methods modeled, Room & Pillar has a lower
descriptions of the most common methods. 1.1.3.1 Open-pit mining Open-pit mining is a type of strip mining in which the ore deposit extends very deep in the ground, necessitating the removal of layer upon layer of overburden and ore. In many cases, logging of trees and clear-cutting or burning of vegetation above the ore deposit
Heap leaching is an industrial mining process to extract precious metals, copper, uranium, and other compounds from ore via a series of chemical reactions that absorb specific minerals and then re-separates them after their division from other earth materials.
Iron-ore mining methods vary by the type of ore being mined. There are four main types of iron-ore deposits worked currently, depending on the mineralogy and geology of the ore deposits. These are magnetite, titanomagnetite, massive hematite and pisolitic ironstone deposits.
