RWANDA / TANTALUM & NIOBIUM MINE / 2004
DOVE Equipment & Machinery Co., Ltd. supplied processing plant to Kigali/Rwanda for recovery of tantalum & niobium concentrates. The plant configuration was customized and designed based on the ore condition of the designated area, which mainly consisted of concentrates in placer forms of detrial material, composed of mixture of medium to heavy clay distributed in layers/pockets, and with light to medium clay on upper levels and heavier clay concentration on lower levels, prior to bedrock. The plant is designed for hydraulic-based mining, open cast exploitation of alluvial ore deposit with ore throughput capacity of 400 m3/hr (cubic meters per hour), configured with direct feeding method by heavy earth moving equipment as well as utilizing monitors and educing method to feed the recovery plant. The proposed system is configured for maximum efficiency and production in view of minimum expenditure and includes equipment as follows: Feed-Ore Station, including Feed Hopper and Hydraulic Cannon, Trommel Classifier (Cone Type), Jig Concentrators, and VBS® Concentrators for recovery of concentrates, slurry pump for slurry feed.
