SJ Series Double-impeller Leaching Tank

The SJ Series Double-Impeller Leaching Tank is built for slurry agitation in cyanide leaching and related gold recovery flowsheets, as well as cyanide-plant wastewater treatment where controlled mixing is required. In a gold plant, it is commonly applied in carbon-in-slurry and cyanide leaching circuits and is typically installed with supporting equipment such as carbon screens, carbon-in-pulp systems, and other auxiliary process components.

Each tank uses a double-impeller arrangement to circulate slurry, keep solids suspended, and maintain consistent pulp density throughout the vessel. Air is dispersed through the tank so gas distribution remains even and bubble size stays fine, which supports leaching reactions and helps maintain stable operating conditions over varying feed characteristics.

That consistency matters in day-to-day operation. Stable circulation reduces the risk of dead zones, improves slurry-to-reagent contact, and helps maintain repeatable leaching and adsorption performance across shifts. The combination of larger impeller diameter with lower revolutions per minute (RPM) is intended to support effective mixing while limiting unnecessary power draw and carbon wear in circuits where carbon is present.

The SJ Series is a strong fit for operations running gold cyanide leaching, CIL, or CIP-style integration where agitation tanks must work reliably with upstream classification and downstream recovery equipment. It is also used in metallurgical, chemical, and light-industry applications where large-volume slurry mixing and aeration are part of the process requirements.

Model selection typically starts with tank diameter × height, effective volume, impeller RPM, and impeller diameter, then confirms feed and discharge piping sizes and the matched reducer model, speed ratio, and motor power. Use the table below to compare sizes and drive packages and to align tank volume and agitation duty with your target residence time and slurry properties.

If you share your circuit type, target throughput, slurry density, and any constraints around piping or installation footprint, Bros Dirt Diggers can help you narrow the SJ Series model range and confirm integration with your carbon screens and downstream process equipment.
