Why heap leach nickel laterites?

2.2.1.3. Koniambo. Glencore Xtrastra's Koniambo project (see Fig. 2.3) in New Caledonia commenced production in 2007 and it was 6 years later before the first metal tap was carried out. The first commercial grade FeNi was tapped just after this in April 2013 some 4 years later than planned.

IMPLEMENTATION OF THE FIRST COMMERCIAL SCALE DC

The selection of DC Furnace technology for laterite smelting can be reduction stage and 2 x 80 MW DC furnaces, for their Koniambo project in New Caledonia[3]. • Alloy granulation of the refined FeNi product. • Slag granulation, since slag pot hauling is an impractical option due to the harsh climatic

Koniambo Nickel SAS – SMSP

Koniambo Nickel (KNS) is a joint venture whose capital is 51% owned by SMSP and 49% by Glencore. KNS is responsible for the construction, the ramp-up and operation of the Northern metallurgical plant with a nominal capacity of 60,000 tonnes per year, and the mining activity on the Koniambo massif located in Northern Province between Voh and Kon.

† Leading supplier for DC furnaces in the metals industry. Examples of a DC unit are illustrated in Figures 3 and 4. The DC furnace is usually operated with an open arc, which smelts the material within a very short time. The material can be charged via a hollow-electrode system (HES) directly into the arc. Investigations show that the arc is
