01 · Chromite concentrate
Chrome
Chrome concentrate is our largest specified line. We sell Southern African chromite into ferrochrome, the chromium unit your stainless mill needs in the melt. We sell that concentrate to smelters, to traders covering a smelter, and to processors who agglomerate fines before the furnace.
We offer two origins. South African material is in the 40/42 band. Zimbabwean material is in the 46/48 band. Both are concentrate. Our South African sheet is sized at 0–2 mm, the fine fraction a smelter or pellet plant takes from a gravity or spiral circuit rather than lumpy run-of-mine ore.

We quote chrome programmes from 500 to 2,500 metric tons a week, and up to 10,000 metric tons in a month. That is the band we offer. The firm offer confirms what the miner can put on the pad that week.
If you want delivery inside South Africa, we quote DAP City Deep. For export we quote FOB, CIF, or the port basis for Durban, Maputo or Beira. Silica, phosphorus and the chrome-to-iron ratio are the numbers your smelter will look at, so they are on our sheet.
