TIN, LEAD AND COPPER SMELTING AND RECYCLING WITH MONOMETER ROTARY FURNACES Monometer rotary furnaces for the reclamation of tin and lead
have been in particularly high demand recently, 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. Monometer offers a fully comprehensive service from design for special applications through to commissioning and continuous assistance after installation. A typical installation will be commissioned and proven by one of our metallurgical engineers to operate to the standards and performance quoted, and our after sales service will attend at short notice regarding any process-related requirements or other furnace needs. For these reasons Monometer is particularly well placed with the necessary combination of experience backed up by continual development and the highest qualify of manufacture and service, to provide a reliable high performance solution for the client every time. |
