The complex geological evolution of Zambia, together with the abundance and diversity of mineral deposits and other natural resource deposits, are pointers towards the considerable potential for the discovery of new occurrences through exploration based on empirical models driven by known deposits and exploration formulated on conceptual models.

Inferred resources of 9.6 million tonnes grading 0.5% representing 120 million pounds of copper. Complete mineral reserve and resource data, including tonnes, grades, and ounces, as well as the assumptions on which the mineral reserves for Barrick are reported, are set out in Barrick’s Q4 2019 Report issued on February 12, 2020.

Cobalt is a critical and strategic met­ al because of its essential defense­ related uses and the high degree of U.s. import reliance for its supply. Current­ ly, the United States does not produce any cobalt from domestic mines. Most of the U.s. supply of cobalt is imported frcm the African nations of Zambia and Zaire (1).4 Recent trends ...

Sedimentary rock-hosted stratiform copper or sedimentary copper deposits are important sources of Cu, Co, and Ag (Gustafson and Williams, 1981; Boyle et al., 1989; Hitzman et al., 2005), accounting for ∼15% of the world's Cu resource (Sillitoe, 2012).The Central African Copperbelt is the world's largest and highest-grade sedimentary copper province, with close to 200 Mt of copper produced or ...

Sodium silicate also called water glass ~250 g/t (Na 2 O.xSiO 2 with x: 2.1–2.2, Na 2 O: 30–32%, SiO 2: 66%) is a well-known reagent which is typically used as a dispersant of gangue minerals. It also has the virtue of modifying the viscosity of the pulp.-

About 50 per cent of the cobalt is leached (along with the copper) mainly from the Co 2+ minerals. The other cobaltic minerals need to be reduced to the 2+ state in order for them to leach. This is achieved with controlled reductive leaching. The main reductant used to date has been sodium meta bi-sulphite (SMBS: Na 2S2O5) (Mwema et al). In an ...

Most widespread minerals containing Cobalt; This list of minerals containing Cobalt is built from the mindat locality database. This is based on the number of localities entered for mineral species and is therefore slanted towards minerals interesting to collectors with less coverage of common rock-forming-minerals so it does not give an undistorted distribution of Cobalt mineral species.

Cobalt is a hard, lustrous, grey metal with a high melting point (1493°C). Cobalt is used mainly in production of chemicals (58 percent), super alloys for gas turbine blades and jet aircraft engines, special steel, carbides, diamond tools and magnets. By far, the biggest producer of cobalt is Congo, followed by Canada, China, Russia and Zambia.
