Rare-earth element - Minerals, Ores, Uses: The content of the individual rare-earth elements varies considerably from mineral to mineral and from deposit to deposit. The minerals and ores are generally classified as "light" or "heavy"; in the former group most of the elements present are the light-atomic-weight elements (i.e., …
Project objectives are to compile and examine mineral maps of the known lithium-bearing playas in the U.S., Chile, and Argentina using field and remote sensing data to better understand the mineralogy of these deposits. After mineral assemblages are identified, mineral maps for lithium-rich plays will be compiled using ASTER data.
Ball and rod mills are widely used grinding equipment in mineral processing plants. The two are similar in appearance and grinding principle, but there are differences in structure, performance, use, etc. This article will introduce their similarities and differences and tell you how to choose a ball mill and a rod mill.

The ball mill is the key equipment for crushing materials after they are crushed. It is widely loved by people in mineral processing, building materials, chemical, and other industries because of its characteristics of high efficiency, energy saving, intelligence, environmental protection, low carbon, durability, and long life.
A ball mill is a kind of grinder that grinds and blends materials for the purpose of mineral processing, paint production, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: the balls are released from the top of the shell and then crush and grind the material to fine powders.

Four conventional mineral deposit types—carbonatite, alkaline igneous, heavy mineral sand, and regolith-hosted ion-adsorption clay deposits—currently supply …
Rare earth minerals are comprised of 17 different elements. Despite what the name suggests, the elements themselves are not particularly rare. However, they are challenging to mine as they do not generally accumulate into rich ore bodies. The most common use of rare earth minerals is as a magnet in electronic devices and transportation methods.
A mineral previously known only from moon rocks and lunar meteorites has now been found on Earth. Researchers discovered the substance—dubbed tranquillityite after the Sea of Tranquility, where Apollo 11 astronauts landed on the Moon in July 1969— at six sites in Western Australia.
Ball Mill Introduction . There are three main stages to mineral processing in the mining industry.These are: Comminution (crushing and grinding).; Beneficiation (separation and concentration).; Smelting and refining.; Ball mills are employed in the comminution stage as grinding machines (size reduction).The purpose of grinders in the mining industry is …

Ore from Cananea mine is extracted using conventional open pit mining techniques, and then refined further at an on-site concentrator. Ore with more than the mill cut-off grade (0.34%) is reduced to approximately half an inch in large rotating crushers. It is then ground to a fine powder in the ball and bar mills.
