Mining & Smelting HydroFLOW can assist not only with the treatment and prevention of normal limescale – i.e. calcium carbonate, but also with the treatment of non-carbonate scale, such as sulphate and phosphate scale. Non-carbonate scale occurs in a range of industrial applications such as in mining and smelting works, in pipelines and other systems. In this example – a nickel mine and smelting works – a pulp mixture of sulphide concentrate and water was pumped through several pipelines, each one over a kilometre in length. The scale which would accumulate in the pipelines, significantly reducing the carrying capacity and the flow rate, and the pipelines would often become fully blocked in only 6 weeks, necessitating a deep clean. The HydroFLOW was installed on two of the pipelines for a 4
