Typical examples of such industrial minerals include chromite and kimberlite. The method is also used in precious metal and sulphide ore combination processes and in a variety of recycling processes as an auxiliary method.
GTK’s mineral processing unit has extensive experience in different applications of this separation technique.
Laboratory studies usually start with small-scale shaking table tests and mineralogical analysis.
Our pilot plant has several types of spiral separators and full-scale shaking tables for testing. We also have a Knelson centrifugal separator available.
Pneumatic separators, such as a sluice, a jig, and a shaking table, can be used for dry-process application studies.
The basics of heavy medium separation can be studied with an Erickson cone and a small sample size. The pilot plant also has a drum separator that is used for pebble-sized materials (75 mm) and a dynamic Dyna Whirlpool separator (DWP) for fine-grained materials (-15 mm). A variety of ferro-silicon fractions are used as medium in separation.
