The ZipaTank^TM tank can be provided as a complete package inclusive of the agitator, impellers and agitator support beams. Interconnecting launders can also be provided for multiple tank trains. Other ancillaries are available as described below:

Baffles

The ZipaTank^TM includes modular baffles as required, depending on agitation requirements. Baffles are provided in modular sections for connection to the vertical tank panels via bolt holes, which are pre-cut into the vertical tank panels.

Launders

Where the ZipaTank^TM is to form part of an interconnected series of tanks, such as in a leaching application, then modular launders and internal slurry risers allow transfer between each tank.

Inter-tank slurry transport launders are designed for smooth slurry flow, and are configured to allow easy tank bypass for maintenance. All launders have removable lids for inspection and maintenance, and can be isolated using gate valves.

Slurry Riser

Slurry risers are available for inter-tank slurry transport to prevent short circuiting during mixing. Slurry risers are manufactured out of semicircular pipe and welded to the vertical panel prior to transport.

Agitators and Support Structures

The ZipaTank^TM can be designed to withstand the buckling loads associated with overhung agitators and other structural steel components, to allow mounting of these components directly onto the tank shell. The agitator and its support beams will bolt to the top of the tank and be supported by load bearing channels pre-fabricated into the side of the tank panels.

Gas Spargers

Tanks can be used as reaction vessels that employ gases during processing. The ZipaTank^TM can be fitted with gas spargers to inject oxygen/air into the solution or slurries. Xstrata Technology provides HyperSparge^TM oxygen spargers, which are designed to be easily inserted into the ZipaTank^TM without internal support in the reactor vessel. The HyperSparge^TM nozzle allow air/oxygen injection into the tank at supersonic velocities, resulting in a fine mist of bubbles for efficient transfer of oxygen into the solution/slurry phase.

Tank Lids

Modular panel lids can be supplied for the ZipaTank^TM. Lids are provided in sections for easy assembly and are manufactured out of a range of materials, from lightweight alloy steel through to FRP. These lids are designed in sections, to allow easy removal.

Tank lids can accommodate off gas vents and agitator shaft seals where required.

Manholes

Manholes are built into the vertical panels as required. These allow for personnel to enter a drained ZipaTank^TM to carry out inspections and maintenance.

Tank Overflows

Tank overflow boxes and overflow pipework can be built into the vertical panels prior to transport, or provided as flanged assemblies for erection on site.

Scuttle Valves

Scuttle valves and associated nozzles can be incorporated into the design of the ZipaTank^TM to suit a clients requirements.

General Valves and Nozzles

General valves and nozzles, such as pump suction nozzles, can be incorporated into the design of the ZipaTank^TM to suit a clients requirements.
