Hutcheson VISIT TO GAF CORPORATION HYDE PARK VERMONT This past Monday January 31st J. 0. ^ by and I visited the GAF Mine at Hyde Park We went there to discuss the proposed EPA regulations and also to assess the fairly operation They were very courteous and in answering questions . open PRODUCTION Their production in 1971 wa so 2,000 - 3,000 3,000 tons Group IV 20,000 -21,000 tons Groups V and VI 23,000 a_i tons Group VII = TOTAL 46,000 tons They have been on a five week since early December tonnage 1971 but expect to produce approximately the same of fibre in 1972 o , . . They mine 1 million tons of ore per average recovery of 4.6 year with an ao AINING ~ They have two main pits which we visited and three smaller ones To date their hauls have been very short for both - ore and waste and usually with the grade in favour of the load Their / ratio in recent years has been 1 or @ - 1972 little higher They are forecasting 1 2 or less for the next few years for and Pits and roads were in extremely good shape and the pit mining seemed reasonably efficient They quoted a cost of 52 cents per ton for all mining plus primary and the oa Loe first wet stage of secondary crushing For equipment they -. have four electric shovels - approximately 3 cubic yard ot size three ton trucks with one ton stand s and oo eran TE ER A EW ence A Pom Oe rete me ee cere cree . e Le = atone, ; . J.R.M. Hutcheson Visit to GAF -2- Reich drill I was told that the main pit adjacent to the plant waS engineered another 100 feet in depth and assuming this to be solid ore they have about 4 million tons - or .. four years are supply in this area with little or no waste removal I would guess there is probably the same amount of ore developed in the other pit So. . . q . . . . MILLING The ore is crushed through a jaw crusher and a Symons m's Cone end put on a wet ore stockpile with a reclaim et tunnel and two draw points They did say that they had * ; much trouble with freezing during the winter months crushing The ore then to two horizontal dryers which havecrushing no dust control then to another stage of cone plus impacting with J- fiberizers and Simplicitiys Simplicitiys . Despite the fact that we thought they had made some effort to clean up the mill for our visit it was a real jackpot Tailings are conveyed from the mill by operating conveyor with three stackers around the top a of the pile This past year extra rock screening capacity was put in a for low grade ore less than 3.5 They were rather embarrassed as since the installation of this screening ~ they have not been able to find any los grade ore 7 - Nad. ; ENVIRONMENTAL CONTROL We discussed the proposed EPA regulations with the CAF 7 : | strictly people and they said if these regulations were enforced as proposed they would probably go out of : ; . business They have estimated very roughly that it will cost 250,000 to put dust control on the dryers -and tailings transfer pointe I think this figure looks low They have installed a Pulsaire collector on one points of the tailings transfer doing a good job . and it seemed to be -. . - woe _ While we were in the office a quote uss received in the mail from - to diagnose and recommend corrective action - for environmental control It was for 30,000 and staggered them no and They were visited this past September by the U.S. Bureau of Nines personnel from on : ne nmr gemrm rams 2m ann me fe ener ae gene et Pe i .
