Physical and Chemical Beneficiation of the Egyptian Beach ...

The behavior of monazite with the electrostatic field setting of the roll‐type electrostatic separator was studied for the different variables of the separator. Most of the monazite grains are reversible negative and are attracted towards the positively charged static electrode. Using wet gravity concentration, both low and high intensity magnetic separation, and electrostatic separation techniques, a high grade concentrate assaying 97 wt. % monazite

Using a magnetic separation method at various magnetic intensities, paramagnetic minerals, ilmenite (0.8 T magnetic product), and monazite/xenotime (1.0–1.4 T magnetic product) were recovered selectively. Using a magnetic separation result, the beneficiation process was conducted with additional gravity separation for zircon to produce a

Monazite - Wikipedia

Monazite can be isolated as a nearly pure concentrate by the use of gravity, magnetic, and electrostatic separation. Monazite sand deposits are inevitably of the monazite-( Ce ) composition. Typically, the lanthanides in such monazites contain about 45–48% cerium , about 24% lanthanum , about 17% neodymium , about 5% praseodymium , and minor quantities of samarium , gadolinium , and yttrium .

Monazite - CONCENTRATION OF MINERALS

Other major monazite sources are heavy mineral sands from so-called placerdeposits which are usually mined by dredging or scraping, followed by screening and concentration in spiral concentrators. Mineral concentrates are then washed, dried and fed into magnetic separators to remove e.g. ilmenite and other magnetic minerals. In a subsequent step electrically conducting and nonconducting heavy minerals are typically separated in electrostatic plate separators

24/05/2000  Preliminary beneficiation of bastnaesite is performed by attrition scrubbing and cycloning of the ore crushed to −1.65 mm. Three-stage cycloning produced an overflow preconcentrate with a 28% REO grade and 72.6% recovery. This product was upgraded by the use of a multi-gravity separator. The grade of the preconcentrate was increased by MGS to 35.5% REO grade with 48% recovery. The

Gravity separation - Wikipedia

Gravity separation is an industrial method of separating two components, either a suspension, or dry granular mixture where separating the components with gravity is sufficiently practical: i.e. the components of the mixture have different specific weight. All of the gravitational methods are common in the sense that they all use gravity as the dominant force.
