Abstract
Abstract A filter separator for wet enrichment of finely dispersed materials comprising at least two filtering tanks made from nonmagnetic material with ferromagnetic filtering elements accommodated therein and adapted for extracting desired materials from the pulp. Mounted in each tank between the filtering elements are electromagnetic coils, and provision is made for a distributor unit for separate supply of pulp and water to each of the tanks, this unit being installed above the tanks with capability of turning about their axis of symmetry.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
134 words
A filter separator for wet enrichment of minerals in finely dispersed materials, said separator comprising: at least two filtering tanks made of a non-magnetic material and disposed about a vertical axis of symmetry, a distributor means for alternate and separate supply of pulp and water into each of said tanks, said distributor means being located above said tanks and supported for turning movement about the vertical axis of symmetry of said tanks, the desired minerals being extracted from the pulp in one of said tanks while the extracted minerals are washed away by water in the other tank; electromagnetic coils arranged in each of said filtering tanks; and ferromagnetic filtering elements disposed in said tanks inside and around said electromagnetic coils to form a closed magnetic core, said coils serving to magnetize said elements.
Claim 2
Dependent Claim
134 words
A filter separator for wet enrichment of minerals in finely dispersed materials, said separator comprising: at least two filtering tanks made of a non-magnetic material and disposed about a vertical axis of symmetry, a distributor means for alternate and separate supply of pulp and water into each of said tanks, said distributor means being located above said tanks and supported for turning movement about the vertical axis of symmetry of said tanks, the desired minerals being extracted from the pulp in one of said tanks while the extracted minerals are washed away by water in the other tank; electromagnetic coils arranged in each of said filtering tanks; and ferromagnetic filtering elements disposed in said tanks inside and around said electromagnetic coils to form a closed magnetic core, said coils serving to magnetize said elements.
Claim 3
Dependent Claim
76 words
A filter separator as claimed in claim 1, wherein each of the filtering tanks comprises two concentric cylinders separated by a space adapted for collecting the processed pulp, each said tank including a conical bottom portion having an opening in its vertex, and a magnetic valve in said opening for allowing the removal of water with extracted minerals, the outer cylinder including an upper portion which is provided with an opening to discharge the processed pulp.
Claim 4
Dependent Claim
91 words
A filter separator as claimed in claim 1, wherein said distributor Means comprises a rotatable bowl divided by a concentric partition into two sections for pulp and water, respectively, and two immovable receiving funnels arranged under the bowl, the bottom of each section of the bowl being provided with an opening that is diametrally opposite to the opening in the bottom of the other section to drain pulp and water into said funnels which, upon rotation of the bowl, alternately direct the pulp and water supplied thereinto into the filtering tanks.
Claim 5
Dependent Claim
17 words
A filter separator as claimed in claim 1, wherein said ferromagnetic filtering elements are balls or plates.
Claim 6
Dependent Claim
148 words
A filter separator for wet enrichment of minerals provided with hydrophobic properties in finely dispersed materials, said separator comprising: at least two filtering tanks made of a non-magnetic material and disposed about a vertical axis of symmetry, a distributor means for alternate and separate supply of pulp and water into each of said tanks, said distributor means being located above said tanks and supported for turning movement about the vertical axis of symmetry of said tanks, the desired minerals being extracted from the pulp in one of said tanks while the extracted minerals are washed away by water in the other tank; electromagnetic coils arranged in each of said filtering tanks; and ferromagnetic filtering elements disposed in said tanks inside and around said electromagnetic coils, said coils serving to magnetize said elements, said filtering elements being coated with a hydrophobic film for promoting the extraction of the minerals.
Claim 7
Dependent Claim
148 words
A filter separator for wet enrichment of minerals provided with hydrophobic properties in finely dispersed materials, said separator comprising: at least two filtering tanks made of a non-magnetic material and disposed about a vertical axis of symmetry, a distributor means for alternate and separate supply of pulp and water into each of said tanks, said distributor means being located above said tanks and supported for turning movement about the vertical axis of symmetry of said tanks, the desired minerals being extracted from the pulp in one of said tanks while the extracted minerals are washed away by water in the other tank; electromagnetic coils arranged in each of said filtering tanks; and ferromagnetic filtering elements disposed in said tanks inside and around said electromagnetic coils, said coils serving to magnetize said elements, said filtering elements being coated with a hydrophobic film for promoting the extraction of the minerals.
Claim 8
Dependent Claim
76 words
A filter separator as claimed in claim 5, wherein each of the filtering tanks comprises two concentric cylinders separated by a space adapted for collecting the processed pulp, each said tank including a conical bottom portion having an opening in its vertex, and a magnetic valve in said opening for allowing the removal of water with extracted minerals, the outer cylinder including an upper portion which is provided with an opening to discharge the processed pulp.
Claim 9
Dependent Claim
91 words
A filter separator as claimed in claim 5, wherein said distributor means comprises a rotatable bowl divided by a concentric partition into two sections for pulp and water, respectively, and two immovable receiving funnels arranged under the bowl, the bottom of each section of the bowl being provided with an opening that is diametrally opposite to the opening in the bottom of the other section to drain pulp and water into said funnels which, upon rotation of the bowl, alternately direct the pulp and water supplied thereinto into the filtering tanks.
Claim 10
Dependent Claim
17 words
A filter separator as claimed in claim 5, wherein said ferromagnetic filtering elements are balls or plates.
