When producing one ton of high carbon ferrochrome in SAF, the Tweefontein lump ore has the highest ore consumption at 3200 kg/t, 22% and more than 30% higher than the consumption of Millsell and other ores. At the same time, the Tweefontein lump ore requires the lowest quartzite consumption at 160 kg/t. It is 5% lo205%-22wer than the
This means that 4.3% of the copper present in the ore was lost in the tailings. (d) The % Weight Recovery is equal to the % Weight of the concentrate in Table 1. It can also be calculated from the assay values given in the table, as follows: % Weight Recovery = 100·(2.09 - 0.1)(20 – 0.1) = 10%
The ferrochrome slag production is 1.2 t / t FeCr. It is mainly granulated and the rest is air-cooled. There is an in-house special handling and metal recovery process for the air-cooled slag, where it is made into finished products. In addition to recov-ered ferrochrome, classified slag pr oducts are also made.
