Gromatex, the UK manufacturer of slurry pump spares and wear parts is celebrating after an overseas trial produced exceptional results for a South American company.
Pan American Silver Corp trialled Gromatex wear parts at their Manantial Espejo site in Santa Cruz, Argentina.
Manantial Espejo is an open pit and underground silver-gold mine extracting ore using a combination of conventional open pit and underground mining methods. The open pit operations use trucks and front end loaders, as well as track shovel loading equipment. The underground mining operations use either long hole, cut and fill, or shrinkage mining methods, depending on the geometry of the mineralized zones.
Ore is treated by primary crushing, semi-autogenous and ball mill grinding, agitation leaching, thickening, cyanide leaching thickening, and precipitation of silver and gold in solution in the Merrill-Crowe circuit to produce silver and gold ore from melting of the precipitate. Within this process a large number of Warman AH pumps are used and have given excellent service over the years.
In late 2013 it was decided to trial Gromatex impellers, which are dimensionally interchangeable with the Warman AH, with a view to analysing potential savings on wear parts. Existing parts were lasting 12 to 14 weeks due to the abrasive nature of the liquids being transferred.
Results from this trial have proved exceptional, with wear life increasing to 10 months, and have delivered excellent savings in excess of 300%.
The team at Manantial Espejo are ‘thrilled’ says Matthew Gardner. ‘This is a radical improvement, especially from a maintenance perspective. To be able to reduce maintenance downtime to a third is a game changer.’
Gromatex wear parts are now being introduced in to some of the largest mining and quarrying chains globally and, with continued product development in progress, more and more slurry pump users can look forward to reduced downtime and costs on wear parts.
Gromatex wear parts are distributed in the UK by Atlantic Pumps. For further information and to see how Gromatex can benefit your business call us on 0114 229 3144 or email us by using the enquiry form on the left of this page.
