Case Study - Ciénega

Fresnillo PLC operates the Ciénega mine which is located approximately 200km NW from the city of Durango, Mexico. In 2011 the site underwent a mill expansion, part of their expansion was to expand the gravity gold circuit and increase the overall recovery of gold. The purchase of Gekko’s Batch InLine Leach Reactor (ILR150BA) has enabled Ciénega to achieve consistently high recoveries of gold, >98%, from their batch centrifugal concentrators. The Ciénega ILR is Gekko’s first ILR installation into Mexico. Download File

Technical Paper 048 - Coarse Gold Separation At Bendigo Minings Kangaroo Flat Operation

Bendigo Mining operates a 600,000 tpa comminution, gravity, flotation and leaching processing plant for the recovery of gold from their Kangaroo Flat Operation, in the Bendigo goldfields. The free gold and gold bearing sulphides present are typically coarse grained, and hence are highly amenable to gravity recovery. Download File

Technical Paper 046 - The Role Of Gravity And Intensive Cyanidation In Processing Preg Robbing Gold Ores

A flowsheet has been developed to treat a high tonnage highly preg-robbing gold ore. The ore is lowgrade and fine grained with a high proportion of very fine free gold. The key components of the flowsheet include gravity, flotation, intensive cyanidation with direct electrowinning, and carbon-in-leach of the flotation concentrate. Download File

Technical Paper 045 - Python Underground Processing Plant Critcal Design

The use of continuous gravity recovery in combination with a controlled breakage fine crushing and screening system followed by flash flotation has been incorporated into the Python processing plant. This provides miners with a flexible, robust, low cost, low energy pre-concentration process for the recovery of gold and/or heavy minerals. Download File
