| 中文摘要 | A method of producing potassium chromate directly from chromite ore and KOH was investigated. The chromium recovery was >90% after roasting at 800 degrees C for 3 hours. The KOH-to-ore weight ratio was 1.2:1 and the ore-to-recycling residue weight ratio was 1:1. Production from the roasting process was easy to leach and about 100% of chromate could be recovered through a treatment at 30 degrees C for 30 similar to 40min with a water/solid ratio of 5:1. The obtained chromate solution was purified by addition of conventional compounds. |
