Sawmill recovery rate WOODWEB

Recovery rate is not the most important factor in a production mill setup. When I ran a circle blade we would saw a lot of 12 to 14 inch logs into cross ties and get 4 boards off the sides. My band mill does no better other than the fact that I can take a bit more time and often get a better board and trim a bit better.

How can you increase the copper recovery of your SXEW

Increasing recovery of copper by 5-10 will improve the profitability and decrease the working capital of the plant, with minimal capital outlay. By not removing the recirculating copper load, the overall copper recovery decreases and the overall operating expense is higher due to the fresh acid requirement to E1 and SX-Wash stages.
