![]() ![]() Ore mined at the mining complex is processed at the Kamoto Concentrator (KTC), and the Luilu Metallurgical Plant (Luilu). The assets include the Kamoto underground mine (KTO), KTE UG mine, Etang South UG mine, Kamoto Oliveira Virgule copper and cobalt mine (KOV open pit), and the T17 mine. The main asset of KCC is the Kamoto/Mashamba East mining complex, featuring four underground (UG) mines, two open-pit mine, and two processing facilities. Kamoto Copper Company’s (KCC) mining assets KCC engaged Golder Associates Africa to conduct an independent review of all sections of the technical report made on the material assets owned by KML in Lualaba Province, DRC. It is capable of producing 300,000tpa of copper cathode metal and 30,000tpa of cobalt as a cobalt hydroxide cake.įurther expansion of the plant would increase the cobalt production capacity to 40,000tpa. The whole ore leach (WOL) plant at Luilu features optimised copper and cobalt circuits. The resultant concentrate, along with the concentrate produced from the mixed KOV OP and Mashambe East OP ore, is pumped to the roasters at Luilu for further processing.Īt the Luilu plant, the concentrate passes through three roasters, a leaching circuit, and electro-winning cells to produce final copper and cobalt products. The sulphide ore from KTO is currently treated in a separate sulphide mill and float circuit of the new KTC circuit, with a capacity of 12 million tonnes per annum (Mtpa). ![]() Ore mined at the underground mine is processed at the Kamoto Concentrator (KTC) and the Luilu Metallurgical plant. Transverse longhole retreat with back-fill method is proposed for Zones 1, 6, 7, and Etang South, while the Etang North ore body is mined using longitudinal longhole retreat method with back-fill. Hydraulic or cement hydraulic backfilling will take place once the pillars are mined. Room and pillar method is employed at the OBS and OBI horizons, while the access drives are constructed along strike on the hanging wall contact. Room and pillar, transversal longhole retreat with back-fill, and longitudinal longhole retreat with back-fill are currently applied at the Kamoto underground mine. The project is estimated to contain measured and indicated mineral resources of 77.7Mt, grading 3.92%TCu and 0.48%TCo. Satellite imagery provided by Planet Labs shows the dramatic growth of copper and cobalt mines in and around the city of Kolwezi, in the Democratic Republic of the Congo. The proven and probable reserves at Kamoto mine, as of December 2018, were estimated to be 26.6Mt, grading 3.40% copper and 0.54% cobalt. The Etang South fragment is classified as a broad open synform comprising sedimentary layers in a concave formation, while Etang North is identified to be a rectangular slab dipping 35° to 55° to the east.Įcaille Renversee is identified between Principal and Etang North fragments, while Pringle hosts a moderately open synform. The Principal fragment is a rough L-shape syncline, which comprises flat-lying to gently-dipping rocks in the central and northern areas. The ore body of the Kamoto underground mine is divided into five fragments, namely Principal, Etang South, Etang North, Ecaille Renversee, and Pringle. ![]()
