METHOD AND FLOATING RIG FOR DIAMOND-CARRYING KIMBERLITE PIPE DEVELOPMENT

摘要

FIELD: mining, particularly open cast kimberlite pipe mining. ^ SUBSTANCE: method involves mining ore body by hydromining device of floating dredger; supplying diamond-containing pulp to floating dressing plant, recovering diamonds and transporting reject material from pit to preliminarily prepared plate for following utilization thereof. Ore body is developed by hydromining device reciprocation across total ore body area. Diamonds are recovered by serial pump decomposition, sizing, dressing and conditioning. Residual material is utilized by dewatering thereof in centrifuge and stacking for following usage for building material production. ^ EFFECT: simplified method and rig and decreased power inputs for kimberlite pipe development. ^ 2 cl, 2 dwg
