Description
TECHNICAL FIELD
The present disclosure generally relates to the field of deep sea mining. Particularly, but not exclusively, the present disclosure relates to a system and method of off shore mining for retrieval and extraction of heavy mineral concentrate from placer deposits or other suitable materials.
BACKGROUND
Advancement in technology and rapidly progressing industrialization in the current modern world has spurred an upsurge in usage of minerals and metals. Increasing world demand for minerals mandates requisite of new sources of high-quality’ reserves of heavy minerals concentrate (HMC) which contains metals, minerals and precious stones including gold, diamond, magnetite, rutile, ilmenite, zircon and like. HMC is currently being dredged from continental shelves of global sea floor having placer deposits to cater the increasing world demand for minerals. Placer deposit is a natural concentration of heavy minerals caused by the effect of gravity and weathering processes. Thus, the heavy minerals become concentrated in stream, beach, and lag (residual) gravels and constitute workable ore deposits.
The continental shelves being dredged may constitutes only a very small fraction of HMC from the material recovered from the sea-bed. In generally, the material recovered from the sea-bed is transport to an on-shore processing plant for retrieval and extraction of HMC from the material recovered from the sea-bed. This method is considerably very' uneconomical due to increase in cost arising from supply and maintenance of mining and transportation equipment. Moreover, in on shore processing plant, large volumes of wastes like sand, gravel and silt are separated after retrieval and extraction of HMC. With the increasing environmental and pollutions control norms, disposal of these wastes is stipulated and screened to minimize disruption of landscapes, this in turn add a significant cost for the operation. Conventionally, various off-shore techniques have
PCT-17 29 been proposed in order to obtain HMC by undertaking primary separation of material recovered from the sea-bed, considering the fact that waste disposal may be easier and therefore cheaper than on land. Although greater care must be exercised to ensure that waste is not deposited on unworked reserves on the sea-bed. Furthermore, these conventional techniques don’t provide a system and method which accomplishes the complete retrieval and extraction of heavy mineral concentrate from material recovered from the sea-bed. The conventional off-shore techniques have limitation with respect to production capacities, higher production costs. Also, there is no significant cost difference in comparative cost between on-shore and off-shore techniques except in special circumstances such as distance from a shore base, environmental factors and like.
The present disclosure is directed to mitigate the above stated problems or other similar problems associated with the prior art.

The dredge vessel having thereon a dredging unit adapted for excavate of water bodies and procurement of sediment and debris, at least one gravity separator adapted for separation and exclusion of oversized particles from sediments and debris. Further the dredge vessel comprises of at least one spiral classifier coupled to at least one gravity separator wherein at least one spiral classifier is configured to receive finer particles of sediments and debris to extract total heavy minerals and at least one discharge conduit for tailing of wastes, leftover after extracting total heavy minerals, back into water bodies.

The dredging unit (IT) is substantially a mechanical dredger or a hydraulic dredger or a hydrodynamic dredger, such as a bucket wheel dredger, cutter suction dredger and like. The bucket wheel dredger, employs a plurality of buckets on a revolving chain to dig, scope and remove large quantities of sediment and debris from the bed of water bodies below a plane of movement of the bucket wheel dredger. The cutter suction dredger is equipped with a rotating cutter head, which can cut hard soil or rock, existing in the bed of the water bodies, into fragments. The cutter head is a rotating mechanical device, mounted in front of the suction head and rotating along the axis of the suction pipe. The fragment of sediment and debris thus produced is then sucked in by dredge pumps. Cutter suction dredger can be configured cut the soil according to a pre-set profile.
The gravity separators (12) are coupled to the dredging unit (11), wherein the gravity separators (12) are adapted for separation and exclusion of oversized particles from sediments and debris obtained by the dredging unit (11). The gravity separator (12) is operate by the principle of separation based in difference in size and shape of the particles of sediments and debris. Thus, a finer particle of sediments and debris are obtained by gravity separation (12) of the sediments and debris obtained by the dredging unit (IT). The gravity separator (12) is substantially a vibrating screen or a rotary sieve and like.
The spiral classifier (13) is coupled to at least one gravity separator (12), wherein the spiral classifier (13 ) are configured to receive finer particles of sediment and debris to obtained total heavy minerals. The spiral classifier (13) segregate total heavy minerals and lightweight waste particles, such as sand and silt, from the finer particles of sediment and debris. The segregation is based on the datum that the waste particles have comparatively less specific gravity in comparison with specific gravity of the total heavy minerals. The spiral classifier (13) receive the finer particles of sediment and debris and pass them through a spiral. As the particles of sediment and debris travels down the spiral, the total heavy minerals are segregated from the waste particles.

The dewatering unit (21) is configured to expel water absorbed by the total heavy mineral. The dewatering unit (21) can accomplish removal of water from the total heavy minerals by sun drying or application of ovens and other similar heating or dehydrating equipment. The magnetic separator (22) is an equipment for selectively retaining magnetic materials, so as to separate them from material fed into the equipment. The magnetic separator (22) is employed for separation of desired minerals from total heavy minerals based on magnetic properties of the minerals. Similarly, the electro-magnetic separator (23) is an equipment for selectively retaining electro-magnetic materials, so as to separate them from material fed into the equipment. The electro-magnetic separator (23) is employed for separation of desired minerals from total heavy minerals based on electrical properties of the minerals. The density separator (24) is a device to classify, separate or sort particles in a fluid (air or water) suspension based on the ratio of their centripetal force to fluid resistance. The density separators (24) are substantially a hydro-sizer or a cyclonic separator or an air/Iiquid density separator and like.

Equivalents:
With respect to the use of substantially any plural and/or singular terms herein, those having skill in the art can translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations may be expressly set forth herein for sake of clarity.
It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood by those within the art that if a
PCT-1729 specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to inventions containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances, where a convention analogous to “at least one of A, B, or C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B.”
