TREATMENT OF BLACK COPPER WITH THE USE OF IRON SCRAP - PART I

Treatment of black copper with the use of iron scrap - part I

Currently, there is a large amount of mineral resources not being exploited in large copper minings, a clear example are black copper minerals.These resources are generally not incorpo-rated into the extraction circuits or are not treated, either in stocks, leach pads, or debris.These exotic minerals have considerable amounts of Cu Baby Float and M

Stress concentrators positioning modes and determination of the stress concentration factor using FEM. Establishing cracking scenarios to determine the characteristics of the crack

This paper shows the effects of variable stresses acting on structures, the positioning modes of stress raisers, as well as the determination of stress concentration factor and the establishment of some cracking scenarios in order to determine the main characteristics of the crack.The problem of numerical analysis of various engineering problems is
