· 9Earlier only coking coal was being washed because steel making needs coking coal of ash of 17 to 18%. The raw coal ash in Indian coking coal varies from 25 to 30%. Now-a-days, Min. of Environment & Forests has put restriction on the use of high ash coal in power sectors, which necessitated priority to wash non-coking coal also.
coking coal is around 15% of total reserve and the rest 85% is non-coking coal. Nearly 90% of non-coking coal is classified as F grade coal which contains about 40% ash.

Higher grades of non coking coal will be essential Strategies envisaged " Priority for steel industry and sponge iron of higher grades of non-coking coal (below 12% ash).
· Utilization of non-coking coals in India is on the rise which will create opportunities for beneficiation of coal. In this work attempt was made to study the effect of coal particle size, feed rate and water rate on the ash content and combustible recovery of …
· coking coal or a blend-coking coal. One of the last flotation plants in Natal closed down recently when Durnacol Colliery ceased operations. The only froth flotation plant currently processing fine coal (nominally minus 2 mm in this case) is the one at Tsikondeni Colliery, where a coking coal is produced.
MBE CMT India is also proud to have been associated with setting up of the first two non coking coal washeries set up in our country at Bina & Piparwar, both dedicated for supplying washed coal to the power sector and most of the milestones of the Indian beneficiation sector and now to add to the bouquet, MBE CMT India is about to commission ...
COAL: We supply bituminous coal, coking and non-coking(thermal) coal. The thermal coal is available in A, B and C grades for the local South African market. RB1, RB2 and RB3 are available for export via the Richard's Bay Coal Terminal (RBCT).
· Non Coking Coal does not have any caking properties and it is mainly used as thermal coal for power generation.

· The result, he says, is a cleaner coal with less waste being achieved in a single stage. This saves on capital costs as no further spiral stages are required for cleaning down the line. The approach taken with the Multotec SX10 spiral is to remove the gangue, or mineral containing particles, from the trough in two off-takes.. The first off-take removes ash.
