Executive Summary
This Preliminary Economic Assessment outlines the proposed recovery methods for the El Cajon Borate Deposit in Sonora, Mexico. Laboratory testing has identified a suitable process for recovering a colemanite concentrate with a recovery range of 77-88% B2O3. The proposed flow sheet relies on conventional metallurgical unit operations including scrubbing, de-sliming, crushing, grinding, and flotation, with no novel or untried technology envisioned for the initial process.
Projected operational requirements indicate an energy consumption of 100 kwhours of electricity, 50 cubic metres of natural gas, and 2.86 tonnes of diesel fuel per tonne of colemanite concentrate produced. Water usage is estimated at one tonne per tonne of concentrate, with flotation reagents costing approximately $12 per tonne. Process development is ongoing, and additional unit operations may be incorporated if they provide significant technical or economic benefits.
A future stage of the project contemplates the production of boric acid using colemanite-bearing material as feedstock. This would allow for the utilization of lower grade zones, effectively increasing the mine life and resource base. Additionally, in situ leaching of deep colemanite horizons using the Duval process is considered feasible. The report recommends incorporating a boric acid circuit into the pilot plant to gather data for economic analysis and customer samples.
