Five or six trains carry ore from the mine to Kamsar each day Bauxite processing Treatment of the runofmine bauxite consists mainly of crushing and drying before shipment Ore wagons are tipped individually the material being crushed to –100mm before stockpiling After reclaim using bucketwheel stackerreclaimers the ore is dried from an average of 125 moisture to 67 for shipping

The mining process is the first step in the production of aluminium Bauxite ore is found in a layer up to four metres deep in the form of small red pebbles called pisolites Bauxite is processed into a white powder called alumina which is then processed at smelters into aluminium

Alumina is then smelted using an electrolysis process to produce pure aluminum metal Bauxite is typically found in topsoil located in various tropical and subtropical regions The ore is acquired through environmentally responsible stripmining operations Bauxite reserves are most plentiful in Africa Oceania and South America

May 18 2018 · Aluminium is produced from one of two sources recycling of aluminium scrap and primary production from ore The main ore for the primary route is b whauxiteich is refined into an intermediate product alumina that is then smelted into aluminium Other uses of alumina include chemical grade applications

Applications include abrasive metallurgical cement refractory and chemical The ore is heated in a pressurised chamber at a high temperature of around 200°C and the aluminium is dissolved and then extracted It is then cooled and seeded before being converted into aluminium oxide which is dissolved at a very high temperature of around 960°C
