Mine specific solutions are important, as it is by no means the case that each operation mining a similar ore type will use the same suite of chemicals. Ores differ widely globally and often in small, but significant ways. But this means there is no single mechanical and chemical configuration that could be classed as “standard” for one ore type globally. For example, Codelco Andina and

Iron Ore an overview | ScienceDirect Topics

R. Stace, in Iron Ore, 2015. Abstract. Iron ore reserves are normally found within a few meters from the ground surface, and most of the major mines of the world are operating an opencut system, which requires little sophistication, except in terms of the equipment used and the quantities needed to be mined for operations to be cost-effective. This chapter will look at case studies that define

Mining Flotation Chemicals Market Global Industry

Mining flotation chemicals are used in mining operations involving flotation of minerals from ores. In this report, the chemicals identified for mining flotation have been collectors, frothers, dispersants, activators, depressants, flocculants and others. Collectors are a large group of organic chemical compounds, which differ in chemical composition and function. Xanthates are the most

Tailings Wikipedia

Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore.Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed.. The extraction of minerals from ore can be done two ways: placer mining, which uses water

What are minerals used for? | Anglo American

Copper Nickel Lithium; Copper was originally refined from its ores to make instruments, weapons, and hunting tools. This popular metal is applied to a number of minerals, such as cuprite (copper oxide) and bornite. Copper is also one of the best conductors of electricity, which is why it’s used to make computer chips, wiring, smartphone displays, and car parts.
