Molybdenum Floatation Cell Replacement

Sacré-Davey was contracted to provide services for two existing banks of Denver flotation #100 (eight cells each) which had reached the end of their useful life and required replacement. Our design approach was to make the changeover with minimal disruption to production. The existing structural support steel was used and reinforced. The tank cells were covered with lids to contain the H2S gas, and a manifold connected with duct work to a new scrubber. The two conditioning tanks were raised and pump boxes and pumps were added to the floor level below the cells to pump concentrates to the thickeners.

Upgraded ratio for operating mines

High Upgrade Ratio for Operating Mine

This confidential active silver mine was able to reject 80-90% of current ore while maintaining 94-96% recovery. Ore sorting had a large impact on project economics by increasing mine tonnage, sorting old waste piles and increasing silver production while lowering milling costs.

Large Copper Molybdenum Greenfield Project

For the American CuMo Mining Corporation, Sacré-Davey performed a scoping study to investigate the technical and economic impact of ore sorting. X-ray based sorting was able to discard 50-75% of coarse material as waste.

Underground Silver Project

Sacré-Davey performed a scoping study to investigate the technical and economic impact of ore sorting at Bayhorse Silver Mine. X-ray sorting was able to discard 75% of coarse material as waste and remaining fines material could be pre-sorted by HMS.

Ore sorting maching

Pilot Plant Design

At Teck’s Red Dog zinc, lead and silver mine, Sacré-Davey developed a detailed design for an ore sorting pilot plant. Engineering and economic studies of full scale ore sorting were also performed.

Machine scoping in the wild

Scoping Study

Sacré-Davey worked with Sherwood Copper and the rest of the Kutcho team to produce a comprehensive scoping study for the optimization and development of the new Kutcho Creek Mine. Sacré-Davey’s responsibilities included all onsite facilities, including the mill building (from the crusher to the concentrate load-out), offices, maintenance shops, stores, camp, water & waste water treatment, and transportation of tailings. Sacré-Davey prepared flowsheets, mass balances and equipment layouts for the mill, together with sizing of key process equipment, including flotation cells, cyclones, pumps and filter process.

Machine sorting pebbles

Pebble Crusher Area Improvement

Sacré-Davey performed a study to remove the existing 350 HP pebble crushing units and replace them with larger 900 HP units, as well as examining the proposed installation of a dust collection system. A new maintenance building was proposed which will be attached to the existing pebble crusher building and will be designed to allow the existing overhead crane to roll through. A new lube area for the new crusher lube units as well as lube storage was proposed. A new MCC building was also proposed which will be located over the new lube area.

A molybdenum mine

Max Molybdenum Mine

For this two-phase project, Sacré-Davey first performed structural checks and designed updates and structural modifications in order to meet code and snow loads at the MAX site. In the second phase, Sacré-Davey provided plant layout and structural engineering services, including a building refit, building and equipment foundations, platforms, and complete mill structures for the 1000 TPD mine.
