Columbite–tantalite grains often show mineral inclusions, which can be enriched or depleted in Nb–Ta (Table 2). Among the first ones are Nb- and Ta-bearing cassiterite (SnO 2), struverite [(Ti,Ta,Fe)O 2] and microlite group minerals. Among the latter are zircon (ZrSiO 4) and Nb- and Ta-free cassiterite. These inclusions show different ...

In addition to removing sulfide by table floatation and separating wolframite by magnetic separation, electrical separation can be used to separate scheelite and cassiterite, the resulting product is tin concentrate. For tungsten concentrates containing rare earths, electric separation can also be used to obtain rare earth by-products. ...
These "droplets" locally incorporate a central "zone" of colorless to purple fluorite and contain W-Nb-rutile (Fig. 5a–f and Table 1); cassiterite may also be present. Fluorite (small anhedral grains) as well as accessory monazite and cassiterite are also found in the fine-grained biotite-feldspar-quartz groundmass.
The Table method is a refined form of gravity separation utilizing a mechanical shaking action that enhances the segregation of ore particles on a table. This method separates particles based on their density and size, which is especially useful for ores such as cassiterite, which are denser and coarser.
The main equipment for placer tin (cassiterite) gravity separation is a mineral jig machine, which has the advantages of large processing capacity and high recovery rate. Sometimes to improve the recovery rate of very fine-grained tin particles, a shaker table is also used.

The reductive smelting of cassiterite (conventional process), which is currently the method of choice for the industrial extraction of tin from cassiterite, faces two major challenges: (1) the difficulty in separating iron oxide, Fe 2 O 3, without affecting the recovery of the metal, and (2) process inefficiencies resulting from equipment ...
Because the density of cassiterite is higher than that of co-existing minerals, the traditional beneficiation process of tin ore is gravity beneficiation. ... So the gravity separation method can use the density difference between the cassiterite and the symbiotic minerals to separate the tin concentrates. ... and -2mm enter the shaking table ...
