Recent developments in Slag-fuming process

Das, S K and Sarkar, S (1969) Recent developments in Slag-fuming process. In: UNSPECIFIED.



IN most lead -zinc run-of-mine ores, the main valua- ble minerals are galena and sphalerite . Two products, namely a lead concentrate and a zinc concentrate are obtained by the differential froth flotation process. The separation is never complete : the lead concentrates contain a certain percentage of zinc and the zinc concentrates contain some lead. The indigenous source of lead-zinc ore is the Zawar Mines situated at a distance of about 50 km from Udaipur, Rajasthan. Zawar Mines are located in one of the oldest lead, zinc and silver zones of the world. The underground working is at present being carried out in the Mochia Mogra and Balaria Hills area of the mines . The lead concentrates and zinc concentrates are produced by the differential froth flotationprocess. The lead concen- trate contains 72--75 per cent lead, 5 ' 3 per cent zinc and 22 oz/ton of silver. The zinc concentrate contains about 55 per cent zinc, 1 per cent lead and 5 oz ton of silver.
