5 Reasons Why the World Needs Mining …And Always Will
The mining industry is driven by fundamental forces. The population, urbanization and income growth will demand more buildings, cars, and consumer products, thereby increasing the needs for mined products as the building blocks of this growth. Urbanization is a growth force for mining activities.

Mineral Processing
Mining and mineral-processing industries producing lithium minerals, metals, and salts contribute to the lithium burden in the environment. The processing of lithium-containing minerals such as spodumene, in general, comprises crushing, wet grinding in a ball mill, sizing, gravity concentration, and flotation using a fatty acid (oleic acid) as the collector.

Mining and Extraction: Oxide Ores
Copper is refined from ores in the ground, either through underground or open-pit mines. Most of the copper ores mined today are oxide or sulfide ores. Extraction of sulfide ores is covered in more detail in Copper Mining and Extraction: Sulfide Ores (11–14), but is introduced here because an important by-product of this process is used for the extraction of oxide ores.

Pressure to decarbonize: Drivers of mine-side emissions | McKinsey
Low-grade ore requires energy-intensive processing before shipping to steel furnaces. While fugitive methane mostly impacts coal miners, differences in ore grades could also impact other mining operations, as lower ore grades drive higher material movement and therefore fuel consumption.

Dealing with low-grade ore – Process productivity
Mining, handling and processing low-grade ore in mining and mineral processing operations is resulting in higher costs and lower profits. While this is a widely acknowledged issue, solutions have so far been limited. New technologies now being developed are giving operators options to divert low-grade ore at multiple stages of their operation.

Particle Analysis in Mining and Minerals
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.
