Solutions for Dry Tailings plant

Dry tailings produced after tailings are dewatered with filtration after thickening. When keeping unit costs low in terms of CAPEX and OPEX, equipment sizes are increasing. Same applies for filtered tailings handling starting from receiving of filtered cake and conveying that for further processing.

The material handling of Dry Tailings Plant considers conveying the filtered cake to the final Tailings Storage Facility area with overland conveyors. Overland conveyors are especially suitable for long-distance conveying. The final distribution of tailings in the area takes place with a stacking conveyor system. Typically, filtration plants are equipped with emergency pile stackers in order to keep plant running during maintenance break.

Laitex’s material handling system of Dry Tailings Plant is designed to support the requirements of the mine and the concentrator. These consider dry tailings production rates and capacity, variability, logistics and production targets. Based on the specifications, Laitex evaluates and designs the most suitable solution for material handling in Dry Tailings Plant.

Filter Cake Discharge system

Receiving tens of tons of dry tailings in short discharge cycle requires robust and reliable filter cake discharge conveyor. Hereby, we tailor all our discharge conveyors according to the Dry Tailings Plant’s needs.

In case batch operated filter is applied, one of the key requirements for such system is to turn batch receiving to continuous and steady material flow. Right sizing and meeting filter operation cycles is crucial to meet process requirements.
