New Techniques In Hydraulic Mining

The practice of transporting an ore or matrix from a pit area to the plant process area by means of a hydraulic pipeline has long been used by the mining industry. The industries which have classically used hydraulic transportation of ore to the plant include the phosphate mining industry, the heavy minerals mining industry, the clay mining industry, and the sand mining industry. As the advantages of this method become better known throughout the mining industry as a whole, and as techniques and expertise improve, its use will undoubtedly spread. Its use is presently being contemplated in iron mining diatomaceous earth mining, and several industries where massive removal of overburden is a predicate to economical mining. The widely recognized advantages of hydraulic transport at ion of ore from the pit area to the mines are: 1) Its relatively low initial capital costs. 2) Its speed of relocation at the mine site. 3) The washing and scrubbing action given to the ore by its hydraulic passage into the pit pump and the subsequent trip through booster pumps down the pipeline to the plant.
