Abstract
Abstract A liquid carrier having mineral ore in the form of free particles or a salt dissolved therein is contained within a suitable container. A box member which has walls which are pervious to the liquid by virtue of apertures formed therein or the porous nature of such walls is filled with a collection material such as carbon which may be in the form of filaments or particles. This box member is suspended in the liquid carrier. An elastic member which may be a plate of steel has an orbitting mass oscillator attached to the top end thereof. This elastic member is suspended in the liquid in opposing relationship to the box member. The rotor of the oscillator is rotatably driven so as to generate sonic energy in the elastic member. The carbon particles provide an electrode of an electrolytic system such that the mineral in the carrier, e.g. gold migrates to the carbon particles and deposits thereon. The sonic energy enhances the migration of such mineral particles to the collection material and also tends to clean off impurities such as fine clay from the carbon. Further, excess accumulations of mineral are peeled off from the collection material and dropped to the bottom of the container from where they can easily be removed.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
84 words
A method for winning a mineral from a liquid carrier comprising the steps of: immersing a collection material in a liquid carrier containing a mineral, said material being adapted to attract said mineral for collection on the surface thereof, and transmitting sonic energy to said liquid carrier, the mineral migrating to the surface of said collection material, the sonic energy facilitating the migration of the mineral and causing foreign matter and mineral collected on the surface of said collection material to be separated therefrom.
Claim 2
Independent Claim
84 words
A method for winning a mineral from a liquid carrier comprising the steps of: immersing a collection material in a liquid carrier containing a mineral, said material being adapted to attract said mineral for collection on the surface thereof, and transmitting sonic energy to said liquid carrier, the mineral migrating to the surface of said collection material, the sonic energy facilitating the migration of the mineral and causing foreign matter and mineral collected on the surface of said collection material to be separated therefrom.
Claim 3
Dependent Claim
42 words
The method of claim 1 wherein said sonic energy is transmitted to said liquid carrier from an elastic member suspended in said liquid carrier opposite the collection material, said elastic member being sonically driven by means of a sonic oscillator attached thereto.
Claim 4
Dependent Claim
22 words
The method of claim 2 wherein said elastic member is driven at a sonic frequency at which said elastic member vibrates resonantly.
Claim 5
Dependent Claim
13 words
The method of claim 2 wherein said oscillator is an orbiting mass oscillator.
Claim 6
Dependent Claim
32 words
The method of claim 2 wherein said collection material is contained within a box member having walls pervious to the liquid carrier, said elastic member being positioned directly opposite said box member.
Claim 7
Dependent Claim
28 words
The method of claim 1 wherein said liquid carrier comprises a leaching solution and said mineral comprises gold salts dissolved in said solution, said collection material comprising carbon.
Claim 8
Dependent Claim
28 words
The method of claim 1 wherein said liquid carrier comprises a leaching solution having ore particles remaining therein, the sonic energy aiding the leaching of said ore particles.
Claim 9
Dependent Claim
127 words
Apparatus for winning a mineral from a liquid carrier comprising, a tank, a liquid carrier containing a mineral contained in said tank, a box member having liquid pervious walls containing a collection material adapted to attract said mineral for deposit on the surface thereof, an elastic member immersed in said liquid carrier and positioned directly opposite said box member, an orbiting mass oscillator attached to said elastic member, and means for driving said oscillator at a frequency so as to set up sonic elastic vibration of said elastic member, sonic energy being transmitted from the elastic member to the liquid carrier to facilitate the migraiton of mineral from the carrier to the collection material and separate foreign matter and mineral from the surfaces of said collection material.
Claim 10
Dependent Claim
127 words
Apparatus for winning a mineral from a liquid carrier comprising, a tank, a liquid carrier containing a mineral contained in said tank, a box member having liquid pervious walls containing a collection material adapted to attract said mineral for deposit on the surface thereof, an elastic member immersed in said liquid carrier and positioned directly opposite said box member, an orbiting mass oscillator attached to said elastic member, and means for driving said oscillator at a frequency so as to set up sonic elastic vibration of said elastic member, sonic energy being transmitted from the elastic member to the liquid carrier to facilitate the migraiton of mineral from the carrier to the collection material and separate foreign matter and mineral from the surfaces of said collection material.
Claim 11
Dependent Claim
27 words
The apparatus of claim 8 wherein said orbiting mass oscillator is operable at a frequency such as to effect resonant standing wave vibration of said elastic member.
Claim 12
Dependent Claim
16 words
The apparatus of claim 8 wherein the mineral is gold and the collection material is carbon.
