mining differences between mineral ore and gangue

Ore vs Gangue - What's the difference? WikiDiff

is that ore is rock that contains utilitarian materials; primarily a rock containing metals or gems which -- at the time of the rock's evaluation and proposal for extraction -- are able to be separated from its neighboring minerals and processed at a cost that does not exceed those materials' present-day economic values while gangue is (mining) the earthy waste substances occurring in metallic ore.

2012-4-24  What is the difference between Ore and Mineral? • Ore contains minerals. • All ores are minerals, but not all minerals are ores. • Ores are mineral deposits whereas mineral is a native form in which metals exist. • Ores are used to extract metals economically. Therefore, in ores, large amount of metals are present.

2020-8-25  Gangue: This refers to the rock waste that is mixed in together with the valuable mineral being mined for and needs to be processed. Mineral processing is the separation of the mineral from the gangue. To make sure all the minerals are extracted from the gangue, it is reprocessed a few times.

Gangue Mineral - an overview ScienceDirect Topics

If the gangue mineral in an iron ore is predominantly quartz, reverse flotation is usually used in the cleaning stage to improve the concentrate grade. Figure 9.13 presents a typical flow sheet for processing an oxidized iron ore containing about 30% Fe using a combination of SLon magnetite separators and reverse flotation. The ore is mainly composed of magnetite, hematite, martite, and quartz.

In many cases, the valuable minerals are mixed with gangue, commercially useless material, and the ore must be separated. The first step of many separation processes is comminution (size reduction) followed by classification (separation by particle size) either for further grinding or the next step, concentration of the ore.
