Tailings Recovery and Recycling Processing Flow

Tailings constitute the waste residue discharged following mineral separation operations in ore processing, yet they are not entirely worthless waste. With rapid industrial development and substantial consumption of mineral resources, tailings discharge volumes have progressively increased. The development and utilisation of tailings represent not only a vital task for the circular economy within the mining sector but also hold significant importance for sustainable resource development. Tailings sand production, as one of the primary utilisation methods, requires meticulous equipment configuration for the sand production line. Achieving high-quality manufactured sand and aggregate necessitates a well-balanced production line setup. The tailings recovery and recycling processing workflow is as follows:

To process tailings into aggregate or concrete aggregate, the tailings undergo crushing, sand-making, screening, and washing. The primary equipment in OCP Heavy Industry's tailings sand-making production line includes: vibrating feeders, crushers, sand-making machines, vibrating screens, sand washers, and belt conveyors. Below is a brief overview of the processing flow:

1. Tailings Crushing

First, tailings undergo impurity removal via the vibrating feeder before entering the jaw crusher for primary crushing. They are then conveyed by belt to either a cone crusher or impact crusher for secondary crushing. This stage is determined by the particle size and output requirements following primary crushing. 

2. Tailings Sand Production

If the particle size of crushed tailings meets sand production requirements, they proceed to a vertical impact sand-making machine. This equipment crushes and shapes the tailings, producing manufactured sand suitable for use in aggregate and concrete applications.

3. Tailings Screening

Throughout crushing and sand-making operations, vibrating screens are employed to classify materials. Non-compliant particles are returned to crushing or sand-making equipment for reprocessing.　　

Processed tailings sand can be utilised in concrete production, road surfacing materials, highway and railway construction, as well as serving as raw material for cement, refractories, glass, concrete aggregates, and roofing tiles. The rational utilisation of tailings promotes circular development in the mining industry, while tailings sand production presents new opportunities for mining enterprises.
