MONOMETER at GIFA GIFA 2011 saw a small decrease in the number of exhibitors from 793 to 723, although there is a total increase on space booked to 42,000 square meters. There was an extensive programme of events, seminars and trade symposia. In addition there was an exchange of ideas and information at the “GIFA-Treff” and the World Foundry Organization Technical Forum.
![]() Monometer rotary furnaces for the reclamation of tin and lead, have been in particularly high demand, following a significant rise in commodity prices over the past few years. In particular for tin dross processing, for which up to 99.5% of the metal-bearing material in a charge can be recovered as recycled tin. The smelting process is attractively simple and does not involve salt, so the environmental impact of final waste products is low and will typically pass for low cost disposal routes.
Monometer rotary furnaces are made in the UK to the highest standards of machining and fabrication to ensure reliable alignment of all drive train and furnace rotating components; and all welding, including the integration of spun dished ends, is checked to ASME and/or ISO certification. Following these standards furnace quality is guaranteed, and indeed proven by the many installations worldwide now having achieved in excess of 25 years continuous operation.
The Monometer smelting system extends to accommodate ores of lead, copper and tin, and has been applied in the reclamation of silver from charges of various mixed material. In each of these applications the unique bath depth and rotational programme retain metal fume within the reactive bed of the furnace chamber and effect a rapid cycle and high yield; recoveries of up to 99.5% are quoted in all offers where exhaust dusts are returned to the furnace and this performance is guaranteed subject only to a certified charge assay. |
