Wyoming Range Combined

The Wyoming Range Combined is a phosphorus-phosphates mine located in Lincoln county, Wyoming at an elevation of 10,007 feet.

About the MRDS Data:

All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.

Mine Info

Satelite View

MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Land Status

Land ownership: Mixed
Note: the land ownership field only identifies whether the area the mine is in is generally on public lands like Forest Service or BLM land, or if it is in an area that is generally private property. It does not definitively identify property status, nor does it indicate claim status or whether an area is open to prospecting. Always respect private property.

Comments

Comment (Geology): THE PHOSPHORIA FORMATION IS SUBDIVIDED INTO FIVE MEMBERS BY MCKELVEY (BIBLIOGRAPHY REF. L010), TWO OF WHICH (THE MEADE PEAK AND RETORT MEMBERS) CONTAIN SIGNIFICANT PHOSPHATE DEPOSITS. IN UTAH AND SOUTHWESTERN WYOMING, THE MEADE PEAK MEMBER, AND IN CENTRAL AND NORTHWESTERN WYOMING, THE RETORT MEMBER CONTAIN THE DEPOSITS OF POTENTIAL INTEREST. THE PARK CITY FORMATION OF UTAH AND CENTRAL WYOMING AND THE SHEDHORN SANDSTONE OF NORTHWESTERN WYOMING ARE STRATIGRAPHIC EQUIVALENTS OF AND INTERTONGUE WITH THE PHOSPHORIA FORMATION. THE PHOSPHORIA FORMATION AND EQUIVALENT FORMATIONS ARE UNDERLAIN BY EITHER THE TENSLEEP SANDSTONE, WEBER QUARTZITE, WELLS FORMATION, OR DIAMOND CREEK SANDSTONE AND ARE OVERLAIN BY EITHER THE WOODSIDE OR DINWOODY FORMATIONS.

Comment (Production): RECOVERIES IN THE YIELD DATA SET FOR TWO-PRODUCT MILLS ARE CALCULATED FROM THE TOTAL FEED TO THE MILL AND ARE NOT ACTUAL RECOVERIES WITHIN EACH ORE STREAM. WITHIN _ORE-STREAM RECOVERIES FOR TWO-PRODUCT MILLS PROPOSED IN THIS EVALUATION ARE 89.5 PERCENT FOR MILL K1, DEV SCH 1&2, 87.5% FOR MILL K3, DEV SCH 1, AND 78% FOR MILL K3, DEV SCH 2. EXACT RECOVERIES USED IN CALCULATING PRODUCT OUTPUT TONNAGES FOR TWO PRODUCT MILLS PROPOSED IN THIS EVALUATION ARE 80.6945 PERCENT FOR PRODUCT A, DEV SCH 1&2; 8.8055 % FOR PRODUCT F, DEV SCH 1&2; 26.5321 PERCENT FOR PRODUCT C, DEV SCH 1; 60.9679 PERCENT FOR PRODUCT H. DEV SCH 1; 23.6515 PERCENT FOR PRODUCT C, DEV SCH 2; 54.3485 % FOR PRODUCT H, DEV SCH 2.

Comment (Production): PRODUCTS A, B, C, D, AND E, WHERE PROPOSED IN THIS EVALUATION, ARE ACID GRADE PRODUCTS, AND PRODUCTS F, G, H, I, AND J, ARE FURNACE GRADE PRODUCTS. NOT ALL OF THESE PRODUCTS ARE USED IN THIS EVALUATION.

Comment (Ownership): PHOSPHATE LANDS MAY BE LEASED FROM THE U.S. GOVERNMENT, ALTHOUGH THE FUTURE LEASING SITUATION IS UNCERTAIN DUE TO THE RARE II CLASSIFICATION OF MUCH OF THE AREA (SEE COMMENTS 031-034). CURRENTLY, THERE ARE NO ACTIVE LEASES OR PROSPECTING PERMITS WITHIN THE DEPOSIT AREA.

Comment (Production): THE EXACT YEAR OF DISCOVERY OF PHOSPHATE IN THE WYOMING RANGE IS NOT KNOWN, BUT WAS AROUND THE TURN OF THE CENTURY. EXPLORATION IN THE AREA HAS BEEN CONFINED MOSTLY TO GEOLOGIC MAPPING, AND NO PRODUCTION HAS OCCURRED.

Comment (Workings): ABBREVIATION FOR MINING DISTRICT: WEST. PHOSPHATE = WESTERN PHOSPHATE FIELD.

Comment (Economic Factors): Mining and beneficiation costs for each proposed operation were obtained by applying one of 34 basic mine models and 5 basic mill models developed for evaluating Utah and Wyoming phosphate deposits. Site-specific cost adjustments were made for land acquisition, infrastructure, unusual haulage distance to mill, the presence of multiple beds requiring mining of waste, and mill feed grade and recovery. All costs are in January 1980 dollars. The schedule of costs is based on the assumption that each proposed operation will be independently developed as soon as technically possible after the official January 1979 base date for the current phosphate study. Thus, land acquisition, exploration, and infrastructure capital costs are assumed to begin in 1979. Mine and mill capital costs include a contingency allowance of 15 percent of all other capital costs except working capital. Mine and mill working capital is estimated at 60 days of operating cost. A Bureau costing manual (bibliography data set ref. I030) was used to estimate surface and underground mine exploration, development, reclamation, plant, and equipment capital costs; underground mine operating costs; capital and operating costs for the calcining-hydration mill (if used) and for the flotation sections of other mills; costs of transporting products from proposed mills to existing final processing plants; and access road construction cost. Surface mine operating costs are size-scaled, using scaling factors from Bennett (bibliography data set ref. I001), and others (U.S. office of audit and investigation) for Idaho phosphate mines in 1976 and 1977. Infrastructure capital costs assigned to each proposed mine consist of only those railroad, transmission line, and access road costs which are needed for development of each mine. Railroad cost is estimated by the Richardson rapid construction cost estimating system (bibliography data set ref. I020). Transmission line cost is estimated from typical industry costs (A.W. Watts, 1980, Water and Power Resources Services, personal communication). Access road costs are estimated by using the capital and operating cost estimating handbook (bibliography data set ref. I030). Land acquisition costs are based on typical competitive bids for leases in southeastern Idaho, adjusted for specific deposit grade and thickness. Lease rentals and royalties are based on current rates for federal leases in the western phosphate field. Capital and operating costs for all mills, excepting the calcination-hydration mill (if used) and flotation sections of other mills, are size-scaled, using scaling factors from Bennett (bibliography data set ref. I001), from costs given for a sizing and calcining mill described by de Voto, et al. (bibliography data set ref. R030), vol. 2, appendix d. Site-specific cost adjustments for mill feed grade and recovery are made, using relative cost factors calculated from average cost and recovery curves for altered and unaltered ores (bibliography data set ref. I010).

Comment (Reserve-Resource): PROPERTY HAS BEEN SPLIT INTO THREE SEPARATE DEPOSITS FOR SUPPLY ANALYSIS WITH SEQ NOS. 0560230175, 0560230176, AND 0560230177 THAT ARE RESPECTIVELY NAMED WYOMING RANGE NO 1, WYOMING RANGE NO 2, AND WYOMING RANGE NO 3. REFER TO THESE DEPOSITS FOR THE INDIVIDUAL RESERVES AND PRODUCTION DATA.

Comment (Deposit): THIS MINERALS AVAILABILITY SYSTEM EVALUATION WAS DONE AS PART OF A 1980 STUDY OF UTAH AND WYOMING PHOSPHATE DEPOSITS BY THE INTERMOUNTAIN FIELD OPERATIONS CENTER, DENVER, COLORADO. THE EASTERN PORTION OF THE DEPOSIT EXTENDS INTO SUBLETTE COUNTY. DOMAIN - ABOUT 90 PERCENT OF THE OUTCROP AREA IS CLASSIFIED AS POTENTIALLY UNAVAILABLE ROADLESS AREA REVIEW AND EVALUATION (RARE II) LAND WITH THE REMAINING 10 PERCENT OR SO CLASSIFIED AS NATIONAL FOREST LAND. MINERAL HOLDINGS - ALL PHOSPHATE MINERAL RIGHTS IN THE DEPOSIT AREA ARE HELD BY THE U.S. GOVERNMENT.

Comment (Location): This is not a site record. It is for the entire Wyoming Range. Coded as a district, but that isn't entirely correct either.

Comment (General): PROPERTY HAS BEEN SPLIT INTO THREE SEPARATE DEPOSITS FOR SUPPLY ANALYSIS WITH SEQ NOS. 0560230175, 0560230176, AND 0560230177 THAT ARE RESPECTIVELY NAMED WYOMING RANGE NO 1, WYOMING RANGE NO 2, AND WYOMING RANGE NO 3. REFER TO THESE DEPOSITS FOR THE INDIVIDUAL RESERVES AND PRODUCTION DATA. {In effect, these are duplicate records and should be considered for possible deletion. ABWilson, 6-22-10]
