beach sand a 40 lb bag of silica sand sells for close to 3.00 per bag if i remember correctly.
i will assume that a crushing ball type mill will have to be used priot to separating the carbon from the breccia (granite and beach sand)
i have to leave for work so i will let someone else figure out how many tons of sand we can sell to home depot. or even toronto to spread on winter streets.. (they do get there sand from somewhere)
There are a lot of mining companies that get excited about finding point 6% copper in their pits
copper is what 3.00 per lb now.
albany has 4 to 7 % carbon at min 2.5 per lb
