Resumo
Over the last few years the mining industry has continuously been facing increases in capital and operating costs for new projects; plant expansions and also significant increases in the operating costs of existing plants. To counteract such trend the industry is seeking technologies such as the Vertimill as an option to lower the operating costs of grinding circuits. The benefits the Vertimill offers in terms of lower energy consumption and lower media consumption are well established and documented; such benefits can significantly improve the viability of a new project, plant expansions or upgrading grinding mills that need to be replaced. The paper briefly describes the operation of the Vertimill, recent regrind applications in processing Iron ores where the impact of lower energy and grinding media consumption is very significant because of the large tonnages involved, and also applications as a tertiary and secondary grinding stages of grinding circuits. The paper also highlight the expected role the Vertimill can play in secondary applications and the expected impact on the overall economics of the project.
