A Study of the Differential Seperation of Galena and Sphalerite

The smelting of complex lead ores is a difficult operation, especially when they contain considerable amounts of iron and zinc. When these ores are smelted, all of the zinc, which is valuable and well worth recovering, goes into the slag. With the advent of the flotation processes, and the ability of these processes to concentrate the lead and zinc minerals into separate products, the smelting of complex lead ores was to a great extent simplified.

A Mineral Dressing Study of the Benefication of Philipsburg Manganese Carbonate Ore

The beneficiation of rhodochrosite ore to the extent that it is suitable for nodulizing and subsequent use in the steel industry is intriguing. Such ores from certain mines is relatively easy to beneficiate, but the rhodo-chrosite ore from several deposits of the Philipsburg district has never been successfully up-graded by any of the several known beneficiating methods.

Management Challenges in Nurturing a Safe Work Environment

As engineers, we are trained to use logical, rational problem solving to insure our mines operate at maximum efficiency. We tend to use the same technical approach to design safety into all mining systems. This works well for machines, but not so much for the human component. Recent insights in the field of behavioral economics provide useful ideas for addressing the fact that we are driven by emotions more often than by rational thought. Understanding the nonrational aspect of human behavior is an important piece of any safety system design.
