Method And Apparatus For Treating Tailings Using Alternating Current
US Patent:

13/765924

Assignee:
DPRA Canada Incorporated - Concord
International Classification:
C02F 1/48
US Classification:
204554
Abstract:
There is a method described of treating tailings which are composed of at least some water and clay particles. Within the tailings, at least some water molecules are weakly bond to the clay particles to form a gel like fluid from which water does not readily separate. An alternating current is applied to the tailings to change the electro-chemical properties of the tailings to reduce the weak bonding between the water and the clay particles so that water within the treated tailings is able to separate. Water within the treated tailings is then allowed to separate without further application of electricity. In some embodiments, the treated tailings are allowed to separate through evaporation. Liquid tailings may also be treated with alternating current by applying alternating current to the liquid tailings at a voltage gradient range of 1 to 5 V/cm for a total duration of 24 to 300 hours. The application of alternating current may further comprise applying alternating current at a frequency of 1 to 30 Hz.

International Classification:
C02F 1/463, C25B 15/00, C25B 11/03
US Classification:
205742, 204280, 204284, 204279
Abstract:
A method is provided of treating liquid tailings using electro-kinetics by creating a variable voltage between two electrodes in the tailings. Flocculation and water release from the tailings is induced by establishing an electrical field between the two electrodes. The electrodes are connected to an electrical power source having the variable voltage to create a cathode and an anode. Compacting the flocculation solids and removing further water released from the compacting solids allows for the creation of a compacted material having a desired load bearing capacity.
