Vargas: I have difficulties seeing autoclaving as a 10,000 ton per day process. It is a "small batch process with relatively long cycle times, and since pressure is developed, you need a pressure vessel which is more problematic as the size of the batch increases. We are told that leaching at a relatively tepid temperature of 140 F is sufficient (source one of CL's posts). Autoclanving a ton of material to extract 80 to 100 bucks of goodies might not be cost effective. Mining is of course different, but in most types of businesses I have been in if you COGS is more than 50% of your selling price, it leaves little room for overhead and profits. Since there are no marketing costs in mining you probably can get as higgh as 75% COGS/ASP to reach breakeven. We could check these numbers at established mines.
