Recent process developments in beneficiation and
Gravity separation is commonly applied to extract monazite from beach sand. Valuable heavy minerals such as ilmenite, monazite, zircon, and rutile are selectively recovered by related gravity separators. The results showed that the valuable minerals can be effectively concentrated by gravity separation even in poorly liberated conditions.2.1.4 Physico-chemically driven techniques. The extraction of minor components concentrated in the seawater reverse osmosis (SWRO) brines can become a valuable source of target compounds, such as Cs, In and Rb (Ortiz-Albo et al. 2019).Nevertheless, minerals that occur at low concentrations in seawater are difficult to A review of resource recovery from seawater desalination brine

In value terms, mineral fuels are an essential part of the global mining industry. It concerns coal, natural gas, crude oil, and uranium. Since the early 2000s, the volume of extraction of minerals and metals has grown significantly. It is an effect of the dynamic development of Asian countries, mainly China and India.Seawater represents a potential resource for raw materials extraction. Although NaCl is the most representative mineral extracted other valuable compounds such as Mg, Li, Sr, Rb and B and elements at trace level (Cs, Co, In, Sc, Ga and Ge) are also contained in this “liquid mine”.Mining minerals and critical raw materials from bittern:

Recovery of strategically important critical minerals from
The ores containing valuable minerals are typically mined and processed to extract the valuable minerals. The extraction of the desired minerals, which often are the host metals, such as copper, iron, zinc, can be accompanied by other metals and minerals as by-products.Flotation: the addition of a compound that attaches to the valuable mineral and floats. Smelting: roasting rock at a temperature greater than 900 o C. This causes it to segregate into layers. The valuable minerals are then extracted. This requires a lot of energy. Extracting metal from rock is so energy-intensive that it's much better to recycle.21.5: Ore Extraction K12 LibreTexts
