The technical report outlines the recovery methods employed at the Cozamin Mine, though the provided excerpt is incomplete. Below is a detailed breakdown of the available information and inferred technical details:
1. Processing and Recovery Methods:
– The report references the mill’s configuration as being consistent with prior technical reports, suggesting continuity in the processing methods.
– The mill processes ore from the San Rafael resource, with increasing tonnages noted since mid-[year not specified].
2. Technical Specifications and Equipment:
– No specific equipment details (e.g., crushers, grinders, flotation cells) are provided in the excerpt, but the mention of a “mill” implies standard comminution and concentration circuits.
– Historical reports likely describe equipment such as:
– Primary and secondary crushing units.
– Ball or SAG mills for grinding.
– Froth flotation cells for copper and other metal recovery.
3. Process Flow and Operational Parameters:
– The flow sheet is not detailed here, but typical operations for copper-zinc-lead-silver ores (common in San Rafael) would include:
– Crushing → grinding → flotation → thickening → filtration → tailings management.
– Operational parameters (e.g., grind size, reagent dosages) are not specified.
4. Recovery Rates and Efficiencies:
– The excerpt does not provide recovery rates, but prior reports may cite:
– Copper recovery: Likely >85% via flotation.
– By-product recoveries (e.g., zinc, silver): Dependent on ore grade and circuit optimization.
5. Innovative Techniques:
– No innovations are mentioned, but the note about “increasing tonnages” suggests potential debottlenecking or throughput improvements.
6. Capacity and Throughput:
– The mill’s capacity is unspecified, but the reference to “increasing tonnages” implies scalability or expanded feed from San Rafael.
7. Key Technical Challenges and Solutions:
– Challenges may include:
– Ore variability from San Rafael, requiring adaptive process control.
– Tailings management due to higher throughput.
– Solutions are not detailed in the excerpt.
