· A team of Chinese scientists has developed a new process they say significantly reduces the time needed to extract rare earths from ore, and it could also cut industry pollution.
· Mining rare earths is tricky, both environmentally and economically. The prospectivity of a resource is determined by several factors, including grade, cost of processing, impurities and the relative concentration of the rare earth elements in greatest demand.
The rare earth mining and smelting process can release airborne fluoride which will associate with total suspended particles (TSP) to form aerosols that can enter human respiratory systems and cause damage and respiratory diseases. Research from Baotou, ...
· Lynas Corporation Limited, together with its subsidiaries, engages in the exploration, development, mining, extraction, and processing of rare earth minerals primarily in Australia and Malaysia. The company holds an interest in the Mount Weld project in Western Australia.

· Longnan County officials say they started to crack down on illegal rare earth mining and smaller mining operations in 2011, but they were only able to finish the shutdowns in mid-2017. These enforcement efforts were part of a long, slow process of consolidation within China''s rare earth industry that has led to six major state-owned companies controlling rare earth mining, processing, and ...

· The mining of rare earth metals occurs mainly in southeastern China, in provinces like Jiangxi and Fujian. But there is also mining as north as Inner Mongolia and as west as Sichuan. Over the last decade and a half, China has also moved to obtain exclusive mining rights in African countries in return for building big-ticket infrastructure projects .
· Pensana is advancing the front-end engineering design (FEED) for the Saltend facility, as well as for its Longonjo rare earth mining project, both of which are expected to be finalised in October.
· Mining rare earth metals is quite different from other kinds of mining. One rare-earth mine produces many kinds of elements, but there are many processes involved and all these processes contribute to pollution. The generation of Thorium, a radioactive element leads to leukemia when it leaches into drinking water.

· The mining of rare earth metals, used in everything from smart phones to wind turbines, has long been dominated by China. But as mining of these key elements spreads to countries like Malaysia and Brazil, scientists warn of the dangers of the toxic and radioactive waste generated by the mines and processing plants.
· The process of mining REEs is ecologically devastating. Processing one ton of rare earth metals releases 2,000 tons of radioactive materials, carcinogens, toxic compounds, acids, and other pollutants into the environment. Since thorium and uranium often occur alongside REEs in nature, tailings from mines tend to be radioactive.
· And radioactive material mixed in with ores could end up being positive: If thorium-based nuclear plants prove viable, expanded thorium mining would also turn up usable rare earth minerals.

The process included material and energy inputs, emissions and land use for the mining and concentration of a bastnasite ore with a rare earth oxide concentration of 6%. Input and outputs were reported from bastnasite ore composition mined in China.
· The mining and refining of rare earths, as in most mining of resources, has environmental tradeoffs. This includes piles of tailings that can create landslides and concentrate hazardous waste, the potential for groundwater contamination, and the CO 2 footprint — although EVs are starting to be developed for mining purposes — the potential for radiation exposure, and more.

Geology and Mining Rare earth elements occur in many minerals but typically in concentrations too low to be refined in an economical manner; the concentration of REEs in the Earth''s crust is estimated to be between 150 to 220 parts per million, which is higher
Rare earth carbonate and rare earth chloride are the main primary products in the rare earth industry, and generally speaking, there are currently two main processes for producing these two products. One is concentrated sulfuric acid roasting, the other is the caustic soda method, hereinafter referred to as the alkaline process.
