The Rare Earth Elements: Demand, Global
The rare earth elements (REE) have attracted much attention in recent years, being viewed as critical metals because of China’s domination of their supply chain. This is despite the fact that REE Under the background of increasingly scarce ore worldwide and increasingly fierce market competition, developing the mining industry could be strongly restricted. Intelligent ore sorting equipment not only improves ore use and enhances the economic benefits of enterprises but also increases the ore grade and lessens the A review of intelligent ore sorting technology and equipment

云母：花岗岩-伟晶岩稀有金属成矿作用的重要标志矿物
云母是花岗岩、伟晶岩中的重要造岩矿物，不仅是整个岩浆阶段的结晶产物，而且也是热液过程的参与者。. 作为层状硅酸盐矿物，层间或八面体位置上可容纳锂、铷铯、锡、铌钽等稀有金属。. 本文结合前人研究积累和作者近年来的研究成果，阐述了云母作为Idiomorphic chromite is the only ore mineral appearing in economic quantities. The average content of the ore is 26% Cr 2 O 3 and the Cr/Fe ratio is 1.55. The Kemi chromium mine is an open-pit mine with a waste rock to ore ratio of 5.5:1. At Kemi, the ore from the mine contains 11% iron and 25.5% Cr 2 O 3.Chromite ore beneficiation: prospects and challenges

A Review on the Beneficiation Methods of Borate Minerals
The modern boron applications have adsorbed the mineral processors’ attention to improve typical boron mineral’s (BM) beneficiation methods. In this regard, dry treatment and pretreatment processes—such as magnetic separation and calcination as environmentally friendly methods, due to their minimal or zero adverse effect on the the use of 1.00 g of potassium ethyl xanthate, 10 g of oleic acid, and 20 g of pine oil per ton of ore. The results of the laboratory experiments on beneficiation of granite-aplites are shown in Table 2. The final concentrates (the non-magnetic fraction of the tailings) have a white color and very weak in-BENEFICIATION OF GRANITES AND FELDSPAR~QUARTZ
