Executive Summary

The Kipushi 2017 Prefeasibility Study outlines the redevelopment of the Kipushi Mine in the Democratic Republic of Congo. The project is currently in the development phase, utilizing existing underground infrastructure refurbished for production. The proposed process plant has a nameplate capacity of 800 ktpa, targeting a life-of-mine average annual zinc concentrate production of 381 ktpa with a grade of 59% Zn. The mine life is estimated at eleven years, producing approximately 2,472 kt of zinc metal.

The processing circuit involves two-stage surface crushing, Dense Media Separation (DMS) to reject dolomitic waste, and a single ball mill in closed circuit with cyclones. Flotation is conducted in two stages to recover copper/lead followed by zinc. The project requires significant infrastructure refurbishment, including a 34 km rail spur to connect to the national network for concentrate export. The study identifies a positive business case with an after-tax NPV of $683M at an 8% discount rate.

Processing Overview

  • Crushing: Two-stage surface crushing (Secondary + Tertiary)
  • Separation: Dense Media Separation (DMS)
  • Milling: Single Ball Mill (900 kW)
  • Flotation: Two-stage differential flotation (Cu/Pb then Zn)

Executive Summary

This report details the recovery methods for the Kipushi Underground Mine, outlining a Dense Media Separation (DMS) and Spiral Concentrator plant designed to treat 9.4 Mt of zinc feed over a 10-year mine life. The process targets the production of 5,296 kt of zinc concentrate at 53% Zn, with a secondary tolling arrangement for 547 kt of copper feed to produce 106 kt of copper concentrate.

The primary processing circuit involves crushing and screening followed by DMS using Ferro Silicon media to separate sphalerite from dolomite gangue. Fine fractions are upgraded via spiral concentrators. Tailings are utilized as underground backfill. The plant includes two 75 tph DMS cyclone plants and a 20 tph spiral plant, with concentrate bagging and rail loading facilities at Kipushi Station.
