It also enables them to guarantee consistent high-quality of product to their customers,\u201d Jens-Michael Bergmann, industrial mineral segment manager at Tomra Sorting Mining, said in a release.<\/p>\n<p>The company\u2019s laser sorting technology also has environmental benefits, due to reduced waste and water use and eliminates the need for hand picking, positively impacting workplace health and safety.<\/p>\n<p>Tomra colour and laser sorters can be deployed in combination to sort by colour, composition and size: companies that serve different industries require precise mineral sorting due to customer requirements.&nbsp;<\/p>\n<p>Mikroman Mining\u00a0uses a combination of the company\u2019s laser and colour sorters to differentiate products based on four qualities.
