14/04/2016· In mining, diamonds are recovered mainly from alluvial deposits which vary widely in character, often cemented; and usually contain large quantities of clay or a sticky slime fraction from near zero to about 50%. Substantial production also comes from Kimberlite pipes and dikes (Blue Ground), a basic igneous breccia, considered generally to be the originating source for

Recent Advances in Understanding the Geology of Diamonds,

Establishing diamond grade is a laborious process that combines bulk assay for diamonds in large amounts of exposed kimberlite (in some cases hundreds of tons) with core drilling of the unexposed kimberlite. The goal of this process is to accurately estimate the size of the kimberlite that could be mined (figure 14), the carats of diamond per hundred tons of rock, and the

the process of diamond mining in a simple flowchart

Diamond mining is a feat which requires precision, care, heavy duty extraction tools, and a substantial amount of monetary investment in machinery, to extract gems from the depths of the planet's crust. As a process, it consists of locating possible diamond deposits and their retrieval, in intact form. More.

THE MANUFACTURING PROCESS Sorting the Diamonds. Rough gem-quality dia-monds are sorted in several ways. The main sorting categories are size, shape, color, and clarity. At the CSO, rough diamonds are sorted by hand and by machine into more than 5,000 categories (Stewart, 1991, p. 3–2). Most diamond manufacturers have far fewer categories, and they use

Recent Advances in Understanding the Geology of Diamonds,

Diamond-free fluids could pass through peridotite into eclogite to crystallize diamond. This process could explain the common occurrence of eclogite xenoliths with diamonds in metasomatic veins (e.g., Shirey et al., 2013). At pressures where diamond is stable, cratonic lithosphere is likely to have sufficient reducing conditions for carbon to exist as diamond. A
