Many of the particles encountered in mining are characterized by sieves (classifiers). Recent advances in computers, cameras, and software make image analysis practical for samples with sizes larger than several microns in diameter. As particle size decreases, sieving and/or dynamic image analysis becomes more arduous or impossible and laser diffraction becomes the technique of choice.

ElenaLuisa Iatan, in Phytorestoration of Abandoned Mining and Oil Drilling Sites, 2021. Abstract. The mining industry has been a significant part of the economy for many decades. Continuous pollution of the environment with heavy metals has been caused by mineral resources exploration and exploitation activities, as well as by processing of ores in factories.
The focus of the mining industry is shifting towards potential new resources in remote areas as a result of decreasing ore grades. Remote sensing technology is an effective and widely established analytical method for geology and mineral exploration and has proven extremely beneficial by providing access to dangerous or previously inaccessible mineral deposits.
What are conflict minerals? "Conflict minerals," as defined by the US legislation, currently include the metals tantalum, tin, tungsten and gold, which are the extracts of the minerals cassiterite, columbitetantalite and wolframite, respectively. Downstream companies often refer to the extracts of these minerals as 3TG.

Silver is a soft, white metal that usually occurs in nature in one of four forms: 1) as a native element; 2) as a primary constituent in silver minerals; 3) as a natural alloy with other metals; and, 4) as a trace to minor constituent in the ores of other metals. Most of the silver produced today is a product of the fourth type of occurrence.

Phosphate mining is an important part of the process of producing chemical fertilizers. The specific processes used to extract phosphate rock depend on the geographic characteristics of the area in which the mineral deposits are loed. Most phosphate mining is conducted as openpit mining rather than subsurface mining.
