摘要： The present invention relates, generally, to a method for electrowinning copper powder, and more particularly to a method for electrowinning copper powder from a copper-containing solution using the ferrous/ferric anode reaction. In accordance with various embodiments of the present invention, a process for producing copper powder by electrowinning employs alternative anode reaction technology, namely, the ferrous/ferric anode reaction, and enables the efficient and cost-effective production of copper powder at a total cell voltage of less than about 1.5 V and at current densities of greater than 50 A/ft2. A copper powder electrowinning process in accordance with the present invention also reduces or eliminates acid mist generation that is characteristic of electrowinning operations utilizing conventional electrowinning chemistry (e.g., oxygen evolution at the anode), which is advantageous.

摘要： A floating transfer vessel provides exterior mooring for a ship adapted to receive loose granular cargo, and interior dry-docking for a plurality of barges loaded with loose granular material within the transfer vessel. All relative motion between transfer vessel and barges, and between automated digging and conveying apparatus mounted in the transfer vessel and barge confines or cargo spaces are eliminated, to permit substantial reduction of working tolerances therebetween without possibility of damage. The reduced tolerances leaves very little grain to clean up requiring no additional independent equipment.

摘要： A floating, barge unloader system by which open hopper barges containing granular materials are rapidly unloaded by picking up, rotating the barge and dumping its contents. The open, loaded hopper barge is positioned above a lowered barge lifting platform and secured to it by latch beams and hydraulic clamps. Compressed air is released into the ballast tanks of the barge lifting platform, forcing the ballast water from the tanks, causing the barge lifting platform with the barge secured on it to rise along guide rails. Hydraulically operated, rotating arms affixed to the support structure upon which the guide assembly is mounted attach to the barge lifting platform and rotate the barge lifting platform with the mounted barge and up and about the guide assembly, including pivot elements located along the sides of said support structure during the pivoting of the barge/platform up approximately one hundred angular degrees. The contents of the open hopper barge are dumped onto conveyor(s), which can be situated in the support structure. Once the open hopper barge is emptied, the barge lifting platform with the emptied barge is returned to an upright position, and the hydraulically operated arms and latch beams and hydraulic clamps are released. The ballast tanks of the barge lifting platform are then flooded, causing the barge lifting platform to sink along the guide assembly, below the floating level of the emptied barge. The empty open hopper barge is then flaoted free from the barge lifting platform.

摘要： The present invention is directed to a system for recovering metal values from metal-bearing materials. During a reactive process, a seeding agent is introduced to provide a nucleation site for the crystallization and/or growth of solid species which otherwise tend to passivate the reactive process or otherwise encapsulate the metal value, thereby reducing the amount of desired metal values partially or completely encapsulated by such material. The seeding agent may be generated in a number of ways, including the recycling of residue or the introduction of foreign substances. Systems embodying aspects of the present invention may be beneficial for recovering a variety of metals such as copper, gold, silver, nickel, cobalt, molybdenum, zinc, rhenium, uranium, rare earth metals, and platinum group metals from any metal-bearing material, such as ores and concentrates.
