Coal sludge was formed during coal washing. It is a mixture of fine particles of coal diffused in water. In the present, coal sludge is not produced any more due to qualitative progress in the washing process. Coal sludge deposited historically in old sludge ponds is currently used for further washing purposes or power purposes.
The highest increase in sludge production came with the introduction of shearer loaders at the end of the 50’s and start of the 60’s. On the other hand, there was a dramatic decline in the 90’s following the reduction of mining and introduction of new technologies of sludge processing.
Exhausted sludge boxes then undergo a standard process of sanitation and reclamation. OKD does not sell coal sludge as a fuel for retail sale.
OKD, a.s., has been currently exposed to fraudulent activity by unknown individuals in Germany.
