RIVERMINER® Plants, exclusively produced by DOVE, are combination of DOVE Dredge and DOVE floating wash plant, designed for the most effective, efficient and economic river mining operations.

RIVERMINER® Plants eliminates the necessity for transporting the dredged material to the shore for off-shore mineral processing, since all material will be simultaneously processed on-shore and on board of the floating plant, this results in great saving in operation costs, faster processing time, higher daily production rate and higher security of the production.

FEATURES:

  • EFFICIENCY: DOVE Dredges provide the most advances dredging technology, which achieves a fully automatic production recovery solution, and deliver consistent operations performance shift after shift.
  • OPTIONAL AUTOMATIC EXTRACTION: DOVE Dredges are configured with feature of extraction module, which eliminates the use of Diver. This results in total security of production, as eliminates access by divers to the production.
  • HIGH PRODUCTION RATIO: DOVE Dredges provide higher ratio of production, as material are recovered automatically, high speed in large volume, without interference by divers, and simultaneously pumped to the floating plant, for final processing and production recovery.

  • ECONOMICAL: RIVERMINER® is the most economical and efficient solution for automatic and continuous extraction, processing and recovery of Gold and Diamonds simultaneously on board, eliminates transport of material to shore for processing.
  • EXCLUSIVE DESIGNS: RIVERMINER® exclusive design for recovery of gold, diamonds and other metals and minerals result in 100% recovery with no loss, down to 40 microns (0.040 mm), (0.0016 inches) particle size.
  • PRODUCTION SECURITY: RIVERMINER® is configured with security system and locking mechanism, which protect production, eliminate unauthorized access to production.

WIDE RANGE:

DOVE Dredges are produced in a wide variety of designs, which can be suction dredges, cutter dredges and bucket dredges, as well as dredges that are customized according the client’s requirements.

DOVE supplies a wide range of dredges. DOVE Dredges are offered as standardized dredging equipment lines, as well as customized dredge designs based on your particular requirements. Our engineers will be working closely with your team to customize a dredging plant for your particular needs.

SUCTION DREDGES:

DOVE Suction Dredges are designed as a dredging mechanism that does not necessitate the presence of a diver, reducing the risk of injury and loss of human life.

DOVE Suction Dredge’s extraction module consists of a powerful arm equipped with a classifying head, which can automatically screen and recover all solid particles, up to 4” (100mm). This extraction module is configured with powerful hydraulic agitators that will support and speed up recovery process of the sand and gravel by creating turbulence on the riverbed. This extraction module is also designed with various working depths, in accordance with the dredging pump’s specifications.

CUTTER SUCTION DREDGES:

DOVE Cutter Suction Dredges are suction dredges equipped with a cutting mechanism at their suction end. The cutting mechanism serves to loosen the hardened material that forms the riverbed to allow its excavation by the suction inlet.

BUCKET CHAIN DREDGES:

DOVE Bucket Chain Dredges are configured with buckets that are attached to a chain. The chain circulates, dragging the buckets along. This motion of the buckets allows for ease of excavation of the sediments on the riverbed. Dredges are also known as Gold dredges, diamond dredges, gold and diamond dredges, dredging plants, dredge mining plants and dredgers.

DOVE Dredges, besides being integrated with DOVE Floating wash plants, can also be designed in conjunction with land-based processing plants based on the client’s requirement.

DOVE is a major manufacturer of Dredging equipment for various industries, including: Mining (Diamond Dredges, Gold Dredges, Sand, Gravel & other Minerals Dredges), Construction, Environmental, Navigational, Recreational, Restoration, Maintenance, Etc.

RIVERMINER®:

RIVERMINER® Plants provide you with the most advanced, efficient and economical solution for simultaneous extraction, processing and 100% recovery of all gold, diamond, gemstones, and other metals and minerals on board, with no loss.\ The floating wash plants are designed in various capacities, in accordance with the DOVE Dredges they are integrated with, and for a variety of applications that match the projects requirements and ore characteristics.
