Stone Mining,Natural Stone Mining Process

Also referred as open pit mining, this process include horizontal or vertical cutting of channels into the rock for extraction of a slice of stone from the large rock. Minerals and stones like coal, gypsum, granite, limestone, dimension stone,sandstone, marble and slate are extracted by utilizing this technique. 3.

Gemstone Mining Techniques — Gemstones and Sustainable

The mining techniques adopted to extract gemstones invariably reflect the nature of the deposit: primary deposits (in hard rocks, worked underground or in open pits) and secondary deposits (found in sedimentary, soft-rock, placers). The mineralogy of a gem dictates the type of geological environment in which it can be found.

Mechanical Pulping an overview ScienceDirect Topics

Mechanical pulping is the original form of pulping. It has been largely replaced by chemical pulping, is still used for lower grade papers such as newsprint, and is the only process used for recycled paper (Casey, 1983a).Mechanical pulping relies more so on mechanical actions to separate and develop wood fibers, rather than using chemical means.

More

The Pulp and Paper Making Processes

Fiber separation in mechanical pulping is less dramatic. In the stone groundwood process, de-barked logs are forced against rotating stone grind-ing wheels that are constantly washed by a stream of water. The ground pulp is then screened to remove course debris, thickened, and stored for the paper-making process.
