What are Tailings - Society for Mining, Metallurgy & Exploration

Tailings are a by-product of mining. After ore containing an economically-recoverable commodity is mined from the earth, that commodity is extracted in a processing plant or mill. After the commodity of value is extracted from the ore material, the resultant waste stream is termed "tailings". Typically, mill tailings range from sand to silt ...

3 Tailings Disposal Methods - Xinhai - Xinhai Mining

At present, there are two main methods of tailing filling goaf: 1. Non-dewatered and cemented full tailings filling. This tailings disposal method mixes the dewatering tailings with cement and flies ash to form the filling aggregate. Then, the filling pulp is sent into the goaf by the pipeline armature, thus filling the goaf. 2.

All crusher types for your reduction needs - Outotec

There are two basic types of jaw crushers: single toggle and double toggle. In the single toggle jaw crusher, an eccentric shaft is on the top of the crusher. Shaft rotation causes, along with the toggle plate, a compressive action. A double toggle crusher has two shafts and two toggle plates. The first shaft is a pivoting shaft on the top of ...

Tailings Management With Paste Thickening - westech-inc.com

Recovering water from a tailing stream and using it again upstream in the plant reduces the amount of fresh water a mine needs. The cost of water is frequently one of the primary drivers for implementing a thickened or paste tailings disposal system. Stacking. Surface stacking is the disposal of tailings on the surface of the ground.

Tailings Belt Filter Press - Metallurgist & Mineral Processing Engineer

Originally the tailings were then pumped to a 1.5 meter belt filter press tor dewatering, producing a cake at 65%-85% solids. A belt filter press consists of two tensioned filter belts which trap the flocculated and partially dewatered tails between them in a wedge zone, then expel the remaining solution as the belts move over a series of rollers.

Solutions for Surface Disposal of Mine Tailings | SpringerLink

Cemented paste tailings (CPT) is a pumpable, flowable, non-Newtonian fluid generally prepared by mixing mine tailings, water, and binder. CPT is generally a nonsegregating mixture with a solid concentration of 70–85% and contains enough fines (at least 15% particles less than 20 microns) to prevent settlement and particle segregation when it is transported through a pipeline for disposal ...
