Waste rocks from gold mining in northeastern Thailand are classified as sandstone, siltstone, gossan, skarn, skarn-sulfide, massive sulfide, diorite, and limestone/marble. Among these rocks, skarn-sulfide and massive sulfide rocks have the potential to generate acid mine drainage (AMD) because they contain significant amounts of sulfide minerals, i.e., pyrrhotite, pyrite, arsenopyrite, and chalcopyrite.

Mining wastes are those wastes generated during the extraction, beneficiation, and processing of ore. Waste rock and overburden are the materials that are removed to access the ore. Tailings consist of ground rock and effluents that are generated during processing of the ore.

2018-8-30 During mining, we will place all waste rock and tailings on engineered liners similar to those used by community landfills or industrial solid waste disposal facilities. During closure, the waste rock will be used to backfill the mine pit. The tailings and any remaining waste
Read More2012-1-1 The production of waste rock are very different at different mines due to the geometry of the orebody, development program of ore exploitation, mining method and mining capacity of the underground mine. If a deposit was exploited by open-pit mining method, waste rocks are produced in the process of stripping.

2017-5-15 Millions of tonnes of ore are processed every year by the mining industry, >95% of which is disposed of in the form of waste rocks and mine tailings. The latter are finely ground rock particles generated during the processing of ore materials and separation of target metal minerals, and are highly reactive because of their small particle size and content of reactive minerals, such as pyrite (FeS 2 ).

Waste rock is also a mine residue that typically consists of overburden and material displaced to access the ore body. Waste rock may even contain very low grades of ore but at levels which cannot be processed profitably. Waste rock management basically involves its removal and storage, which may be temporary or long-term.

2015-9-14 Gold/Auriferous Deposits can be classified into types for which here is a List of 10 Types of Gold Deposits:. Auriferous porphyry dykes, sills, and stocks; Auriferous pegmatites; coarse-grained granitic deposits + albitite.; Carbonatites and carbonatite-related deposits.; Auriferous skarn and gold skarn type deposit.; Gold

2012-12-16 Improper waste disposal is often the largest of mine and refinery pollution Waste is generally categorized into two different types: tailings and waste rock stockpiles. Tailings have the most damage potential because they tend to be composed of smaller, finely milled particles, whereas waste

2018-3-13 Before you stake a claim on a spot where you’ve found a possible gold mine, take a mineral sample to an assayer. Assayers analyze the entire metallurgical content of the rock, which can help you determine whether to file a gold claim on the location. Keep in mind that many rocks contain gold

A total of 50 different minerals are extracted from the mine. The northern part of the mine is rich in phosphates and the central area, where Loolekop was situated, is rich in copper. Copper with the co-products of silver, gold, phosphate, iron ore, vermiculite, zirconia and uranium are extracted from the rocks.
