Deep sea mining tailings disposal is a new environmental challenge related to water pollution, mineral crust waste handling, and ocean biology. The objective of this paper is to propose a new tailings disposal procedure for the deep sea mining industry. Through comparisons of the tailings disposal methods which exist in on-land mining and the coastal mining fields, a new tailings disposal proce...

An alternative process to obtain a high degree of dewatering tailings that produces high-density product is presented in this article. This technology involves the combination particle grain size classification by hydrocyclones (HC) and horizontal vibratory screens (HVS). It makes it possible dewater grade performance. (HC-HVS) recovery water from coarse fraction (sands) through two hydrocyclon...

We conducted a series of column experiments on tailing heap samples from the Picacho mine in California to determine ability native Gram-negative bacteria, Alcaligenes faecalis, leach gold. To mimic leaching using our technique, unprocessed and unsorted tailings mixed grain sizes were placed into columns leached for three weeks with four treatments: (1) deionized water, (2) (3) NaCN by bacteria...
