It's good style for a company to publish its flowsheet(s). As I mentioned earlier this year, Mercator has the best I've seen while WUCC's flowsheet has only appeared on the GO brochure. Perhaps someone can scan that and get it into a post where it's readable.

Maybe there's just one pipe that takes the tailings slurry from the mag circuit over to the flotation tanks. The flowsheet would make this evident.

The spreadsheet has the recovery set at 42% for the copper to match the 1500 tpd input ore and the 25 tpd output con. We don't know exactly what the grade is (% copper in the ore) or exactly where the ore is coming from but the numbers in the spreadsheet should be usably close to actuals, if we knew them.

I do recall July but never heard the 20% CU number - that was the "dirty con" era during which no one could give a good reason for the con not being saleable.

The max recovery % of copper that I've read about is 82%. That was the case with lots of iron coming along with the copper. That was in 1917!

F18, I agree, I am not really concerned about the lower recovery rates as it will be recovered later. My major concern was whether there might be a "bottleneck" in the mag line which might limit production into the future while processing ore from the HT mine. Certainly, when other ores are processed, this would become a moot point when mag percentages are lower, (if it were a valid point to begin with).

As it seems right now, we are cash flow neutral (excluding LTD) which is a rather poor ROI based on mill operations only. Yes, I know they are planning to ramp up production, I just hope they can achieve the higher production rates from the HT ore, rather than reverting to a different ore body to achieve their goals. We know there has been some hurdles in the past and I hope we are over them, I was simply speculating to see if anyone else thought this theory was a possibility.

You and On2 are correct though, in that without true mag production numbers, it is difficult (impossible) to predict whether or not all the mag is being captured or if some might be escaping and going through the floatation circuit. My primary question was if the latter (mag running through the floatation circuit)was true, could this pose a problem as I outlined in my previous posts?

People, don't get me wrong, I am not in any way trying to bash cprk, its management, or workers. I am very pleased with all the progress they have made and I have been "long" for over a year and plan to continue to add to my position based on their ongoing accomplishments. I am simply trying to get a little better understanding of the milling process.

On2them, do you have a copy of the open house flow sheet that could be scanned? If so, could I get a copy? Thanks,
