Diamond Industry Wastes: Mineral Composition and Recycling

摘要

Samples from eighteen kimberlitic bodies of Russia (Archangelsk and Yakutia provinces) and China (Liaonin and Shandong provinces) were investigated. All investigated kimberlites were subdivided into four mineralogical–technological types, according to the data obtained: (1) rocks with dominant saponite (Chidviya and Lomonosov pipes), (2) high-serpentine rocks (Snegopadnaya, Aikhal, Dalnyaya, and Udachnaya pipes), (3) rocks with high levels of carbonate and phlogopite (Chernyshevsk and Botuoba pipes), and (4) rocks with a complex mixed structures (Morkoka, 23 S”ezd KPSS, Nyurba, Mir pipes and pipes of China). A recycling scheme is offered for each type of kimberlitic rocks.
