- Editor's Notes
- [this is a draft to Ritchie attached to Ritchie to TAE 890130 inquiry of cost of plant to treat 500 tons of iron ore per day] 1st Cost of plant for 100 tons of concentrate per day from 40 pct ore is at Allentown $27,000. 200 tons of raw ore is run through. Your ore is richer so 200 tons would give you say 175 tons concentrate hence for 500 tons concentrate daily plant would cost roughly $75,000. 2nd. Can't give figures very closely at present but think money would be made at 60 @ 70 cent per ton crude ore. 3rd. Plant could be put up in two months. 4th. Am will to make a contract with the Co for Iron separating on same basis as our Allentown Contract but not until our mill there has run a week or so that we can get data to calculate on. Mill is now being built. 5th. Will not deal with any others for Canada for couple months at any rate. Let me know about that last iron analysis - was it satisfactory for Sulphur
