Abstract

Kromit cevheri/ konsantresinden krom külçelerini üretmeye yönelik bir usul; kromit cevheri/krom konsantresini oksitlemeyi (1) 900°C sıcaklıktaki bir fırın (2) içinde 1.0 ila 3.3 aralığında olan Cr: Fe oranını kapsamayı, oksitlenen cevheri (4) indirgeyici kömür (5) ve cüruf oluşturucu madde (kireç, silis) (6) ile karıştırmayı, karışımı topak haline getirmeyi (pelletleştirme), topakları bir döner fırın (9) içinde 1.400 ile 1.600°C arasındaki bir sıcaklıkta indirgemeyi, bu şekilde üretilen krom külçelerini (12) bir ayrıştırma ünitesinde (11) cüruftan (13) ayırmayı içermektedir.
