INVESTIGATION OF THE HALDEX (SIMDEX) PROCESS FOR BENEFICA TING COAL REFUSE Hungarian Practice - 1969

Special Research Report SR-80 The successful separation of anthracite refuse into products with more marketing potential would offer a highly palatable solution to the problem of refuse bank reclamation. Several refuse treatment plants in the United States and Europe have been reported which produce a variety of marketable or more useful products from such materials. Perhaps the most versatile operation reported is the Tatabanya Mine Dump Reclamation Plant in Tatabanya, Hungary. This plant uses the Haldex (Simdex) process. The heart of the process is the Haldex Cyclone which employs a heavy media created from the material being processed, and has been very successful in recovering fuel and a variety of other marketable products. Upon personal inspection of this operation by Mr. Kogelmann, it became apparent that while this process efficiently separates the refuse material into several marketable streams, it did not incorporate any technology beyond current off-the-shelf equipment. It is, therefore, the recommendation of this report that a similar type of philosophy and technology be employed to develop anthracite refuse fractions which can be utilized commercially
