Events galore at Outotec · Outotec was voted the winner in the Service and Support category in the category of mineral processing by one of the world's leading industrial magazines, Mining Magazine 2022 for the center launder upgrade project conducted at Minerals Constancia site.
The Humphreys Spiral Concentrator is a simple, efficient gravity concentrator which effects a separation between minerals of the proper size range that have sufficient difference in their specific gravity. …
The basic principle of the design is to optimize the launder's geometry such that energy is effectively removed from the centre of the launder through the cooling water channels in the sidewalls. A Finite Element Analysis (FEA) model is run for every launder design to optimize the geometry. For each client, the design process is similar.
The Humphreys Spiral Concentrator is a simple, efficient gravity concentrator which effects a separation between minerals of the proper size range that have sufficient difference in their specific gravity. This concentrator is a spiral conduit of modified semi-circular cross-section, with outlets for removal of concentrate and middling.
Developments in mineral processing During the recession, the emphasis in the mining industry has been on reducing costs, particularly capital and energy costs, rather than on the development of...
The Center Launder Upgrade resulted in a reduction of 68% for froth surface area and 83% for froth transport distance. The upgrade enables a wide operational range: Lip Loadings up to 1.7 tph/m for cells and Froth Carrying Rates up to 4.2 tph/m2. Optimized operational parameters resulted in improved recovery without excessive water and …
A risk-based design approach using the principles of Six Sigma, has been applied to the design of open channel launders used to convey slurry in mineral processing plants. The variability in design input parameters was defined using a triangular probability distribution for the minimum, normal and maximum design values.
Studies reported by Fourie and van Niekerk (2001) and Steffen (1996) indicated that the mine planning and design process during the life of any mine involves five stages: Obtaining data. Data evaluation, mine planning and design. Construction and development of the mine. Operations.
This paper discusses the benefits of the center launder design which was implemented in bulk flotation circuit of Bagdad Cu-Mo flotation circuit. The last three cells in one of the parallel...
What are launders used for? HDPE launders are plastic holding containers built to move effluent or other chemical products and are predominately used in the Australian mining and resources industry.
A recovery increase of 0.74% Cu and 0.82% Mo was achieved after the installation of a simple center launder upgrade solution at Kennecott, Utah. The objective was to increase the froth collection rate by drastically reducing the froth surface area (FSA) by 38% and the froth transport distance (FTD) by 71% to optimize the froth zone.
This launder design system specifies that the Reynolds number must be greater than 5000 and that the Froude number must not be between 0.8 and 1.5. These re.quirements will …
