Mineral exploration methods vary at different stages of the process depending on size of the area being explored, as well as the density and type of information sought. The most common drilling for mine is diamond drilling. Exploration diamond drilling is used in the mining industry to probe the contents of known ore deposits and potential sites.

MI-SWACO CD-250 centrifuge is designed for the purpose to solve a problem that there is no proper model centrifuge for small drilling process application with a compact dimension, for example, HDD, diamond core drilling for mining. It should meet 3 important points: 1 high separation efficiency, 2 tight space, 3 economic solution. GNLW220 centrifuge is designed for the similar purpose.

Mining exploration is the process of finding ore to mine. Mining exploration methods vary at different stages of the process depending on size of the area being explored, as well as the density and type of information sought.

Diamond drilling is a kind of mining exploration drilling, used in the mining industry to probe the contents of known ore deposits and potential sites. Early diamond drilling opened up many new areas for mining, and was related to a boom in mining exploration in remote locations. Before the invention of the portable diamond drill, most mineral prospecting was limited to finding outcrops at the surface and hand digging.

At the 1st stage of mining exploration, sometimes you only drill a small hole like 100~150mm, not so deep. Because of strict regulation of environment protection, you will have to process the drilling mud flowed from the hole. GN solids control can provide a proper solution for your drilling effluents.

GN mini shale shaker GNZS752 is a good solution for such small treating capacity drilling, its nominal treating capacity is 35m3/h at API60 mesh screen. If you need 10~15m3/h process rate, you can use API100 mesh screen. They can perfectly meet your requirement. You do not need a hydrocyclone because the treating capacity is too small, fine mesh screen can finish the job of hydrocyclone.

GN Solids Control is very professional at drilling mud system, then a client tell us a very simillar application: mud recycling for diamond drilling.  The size of cuttings is the main difference with diamond drilling and oil drilling.
In diamond drilling, the cutting size will generally be less than 10 micron. And it is needed to remove 100% of solids otherwise the drilling will run in to major dramas, in a short period of time.
