TPH Quote 2.pdF; floc sys pic 1.Jpg; floc sys plc 2.Jpg <br />Subject: Dry Floc System for Alma Sleuth Mine <br />Greg, <br />I was good talking to you on the phone yesterday. After we talked, I spoke with Jerry Miller and <br />gave him pricing Information on the TPH Dry Flomrlent Blending and Metering System for Alma <br />Sleuth Mine. Our price quote is based on the information that I received from Jerry and Zane as <br />summarized below. <br />- They are moving about SO yards of material an hour. <br />- The owner estimates there flow at about 3000 gpm. <br />- They screen out 1/2" and above. Most of the heavies drop out drop out <br />in the first 50 R or so after weirs. <br />- This is followed by 3 small settling ponds then a larger fresh water pond <br />where water from the river is pumped into to replenish and water <br />for washing is pumped out of. <br />- They want the mud to drop out In the settling ponds after the natural <br />heavies drop out with clean water flowing back into their fresh water pond. <br />After our meeting I picked up a sample of their slurry. Following is the analysis of that sample. <br />PH ; 7.71 <br />Dry solids SpG : 2.75 <br />Slurry SpG 1.0227 <br />% solids : 3.4527 <br />It took 1 ml of 0.1 % AF-307 to settle 4.75 Inches/Min with a aystai Gear <br />overttow. This dosage converts to 0.1416 poundsli (71 ppm) for clarifier <br />process and 211 ppm for Belt Press dewatering. No coagulant was needed for <br />the clarification <br />Based on the above Information, two quotes are attached. The first is for the TPH Automated Dry <br />Flocculent System and the second IS for the Dry System Plus a Self Contained Stainless Steel <br />Building. I am also Including two Hyrhem Documents pertaining to the Dry Flocculent AF-307. <br />The first being the Technical Data Sheet and the second being the Material Safety Data <br />Sheet. Finally I am attaching several pictures of a TPH Ory Flocculent System that is very similar <br />to system being proposed for Alma. <br />If you have any questions please do not hesitate to contact me. <br />Best regards, <br />Charlie Schulte <br />Tons Per Hour <br />8/7/06 Addendum to Sediment Control System Page 4 <br />
