A process for reducing rocks and concentrating heavy minerals

To obtain minerals suitable for age-dating and other analyses, it is necessary to first reduce the mineral-bearing rock to a fine, sand-like consistency. Reducing whole rock requires crushing, grinding, and sieving. Ideally, the reduced material should range in size from to mesh (an opening between wires in a sieve). The openings in an mesh sieve are equal to 0.007 inches, 0.177 ...

Extraction Techniques for Minerals in Space

Before going any further consider weight, mass, inertia, friction, traction. Inertia not weight is the real problem with moving things and, as this is a function of mass not weight, the lack of gravity is not a real bonus ; Fracturing and evacuation equipment on Earth uses gravity as the hold-down mechanism.

Sedimentary Rocks

Sedimentary Rocks. Rivers, oceans, winds, and rain runoff all have the ability to carry the particles washed off of eroding rocks. Such material, called detritus, consists of fragments of rocks and minerals.When the energy of the transporting current is not strong enough to carry these particles, the particles drop out in the process of sedimentation.
