Arizona's Artillery Peak Manganese Deposits.
Pres At SME-AIME Fall Mtg & Exhibit Denver Colorado 1981 Nov; :8 pages
The Bureau of Mines is conducting research to boost domestic production of manganese. Virtually no mining exists in the low- grade and/or small deposits that occur in this country. One large, low-grade manganese deposit located in west-central Arizona--the Artillery Peak District--was extensively studied and sporadically mined during the 1940's and 1950's. Although manganese mining in the district has been long dormant, recent studies indicate that the deposits may be amenable to economical production by heap and/or in situ leaching methods. A conceptual design for an in situ leaching system features undercutting and blasting a block of ore, leaching with so2, and extracting the manganese as a sulfate or oxide. Possible applications to other manganese deposits depend upon formation permeability and specific manganese mineralogy.
