Due to the large amount of capital necessary to finance these operations, development may be conducted in phases to take advantage of the earliest possible saleable or leasable mineral to help finance the remainder of the development. The brief discussion that follows includes only the primary processes for mineral separation. Has applications for other aspects of the mining industries. Leaching or other hydrometallurgical techniques are used only for industrial minerals to remove minor contaminants of a product or to prepare the mineral surface to meet market specifications. Energy consumption is a major capital and operating cost of mineral beneficiation, and approximately two-thirds of energy processing costs can be attributed to size reduction. Recently developed processes include pressure leaching with ultra-fine grinding, which increases leaching kinetics and metal recovery, thus making pressure hydrometallurgy more attractive.
Mining silver strip tool. Scrapers, bulldozers, drills, shovels, front-end loaders, trucks, cranes, draglines). In 1963 general mills succeeded in producing a copper reagent, lix 63, which in combination with electrowinning led to the first small copper sxew plant in arizona. However, new technologies, such as laser fluorescence scanning and portable x-ray fluorescence, which can directly determine concentrations of elements in rocks, and differential leaching techniques are also being developed and used for exploration. New blasting and ore-handling schemes) and selectively liberate and size minerals. At the next level of magnetic intensity, dry separators are common, and wet high-intensity separators are in everyday use on hematite, a paramagnetic mineral. Preventing automatic fire suppression systems failure on underground mining belt conveyers. Placer mining is used where minerals are found in gravel or sand.

New developments in micro-explosives that could be pumped into thin fractures and detonated should be explored for their applications to in-situ fracturing and increasing permeability for processing. Surface mining today is characterized by very large equipment (e.
