MINERAL PREPARATION OF ORES FROM FRIDAY CREEK

2007-3-23  In the summer of 1973, Glenn Craig constructed a 35-tonlday concentrating mill on Friday Creek near Kan- tishna, Alaska. Ore processed during the summer season was removed while excavating a 42-foot shaft and short drift.

RECOVERING MERCURY FROM CINNABAR-STIBNITE ORE

2010-8-12  This report summarizes the results of laboratory investigations by the Alaska Mining Experiment Station, Juneau, to determine the practicability of treating cin-nabar-stibnite ore by bulk flotation and controlled-atmosphere roasting of the concentrate. Ore from the Red Devil mine near Sleetmute, Alaska, was selected for testing;

gold ore dressing season in alaska

Sometimes open pit mining is used, such as at the Fort Knox Mine in central Alaska. Barrick Gold Corporation has one of the largest open pit gold mines in North America located on its Goldstrike mine property in north eastern Nevada. Other gold mines use underground mining, where the ore is extracted through tunnels or shafts.

Beneficiation of rare earth minerals from Bokan

The purpose of this research work was to study the beneficiation of rare earth ore of the Bokan Mountain Dotson Ridge deposit, located near Ketchikan, Alaska. Rare earth element (REE) composite ore samples from the Bokan Mountain Dotson Ridge deposit were tested using gravity concentration, magnetic separation, flotation, and leaching techniques to separate the REE.
