Orica Minisparge™ System

Orica’s Minisparge™ system comprises a small onsite dissolving tank and a 22 tonne solid capacity sodium cyanide sparge isotainer. This system allows up to 22 tonnes of solid sodium cyanide to be dissolved on the mine site as required and is recommended for all small to medium customers who consume less than 1,000 tonnes per annum within Australia.

ORICA Bulk-Sparging System

The bulk-sparging system was developed to service large scale processing operations requiring in excess of 1,000 tonnes of solid sodium cyanide annually. The Orica bulk-sparging system, pictured above, typically features a dissolving tank, storage tank(s) and a 22 tonne solid capacity sodium cyanide sparge isotainer.

Purpose built isotainers are connected to the onsite dissolving tank that has been pre-filled with water, which is subsequently circulated through the isotainer to rapidly dissolve the cyanide. The resulting sodium cyanide solution is then transferred to the onsite storage tank for use.

The unique sparging systems developed by Orica provide customers with a solution to many of the logistical challenges that were previously associated with sodium cyanide delivery.

Orica offers two sparging alternatives: bulk-sparging to service large-scale mining operations, and the Minisparge™ system developed for smaller operations requiring less than 1,000 tonnes annually.

• World’s best practice in the safe transport of sodium cyanide to mine site

• No loss of containment (of waste solid or dust emissions) due to the closed process

• Reduced manning requirements, as there is no boxed product to dissolve

• Improved ergonomics with ground level discharge, personnel are not working at heights

• Environmentally beneficial through minimisation of packaging

• Safer, more efficient transport to the mine site with minimal LOC risks

• No waste packaging for disposal – no boxes, no bags, no drums

• Faster to sparge bulk containers than to dissolve an equivalent quantity of boxes

• Reduced exposure for workers, improving safety performance

• Abides by UN standards
