Instead, it is sent to either the Chambishi or Nkana cobalt plants, where it is roasted, which allows a higher cobalt recovery than a smelter. Although sulphidization is used in this cobalt flotation, the assays of cobalt and copper in the concentrate track one another, suggesting that the mineral that floats is primarily carrolite.
