Tailor-Made for Your Needs

HN EQUIPMENT filter presses find extensive use in mining industry processing plants due to their notable process flexibility among other advantages. They are commonly employed for dewatering fine coal and coal tailings, as well as for the solid-liquid separation of ore concentrate suspensions obtained through flotation and subsequent separation from mineral by-products. In these operations, metals like zinc, iron, and copper are extracted, while precious metals such as gold, silver, and platinum are also recovered in certain mines in the form of a robust filter cake. Membrane filter presses are the preferred choice in these scenarios, facilitating high cake washing yields and achieving elevated dry matter contents through squeezing processes.

HN EQUIPMENT has demonstrated its efficacy in this domain. Our filter presses, equipped with tailored dewatering technology and specialized design features for these applications, ensure swift cycle times, rapid filtration rates during processing and dewatering of suspensions, and minimal residual water content in the resulting filter cake solids. These characteristics, coupled with optimized and efficient process designs, are crucial for meeting the demand for high capacities, particularly from an economic standpoint.
