Design of an open-pit gold mine by optimal pitwall profiles
INTRODUCTION. In open-pit mining, there is a clear trend of excavating mines of increasing depths (Figure 1a).Owing to the increased efficiency of mining equipment and improved exploration techniques and technology, the ore bodies left to be exploited are deeper (Figure 1b).The deeper a mine is, the higher the effect of pitwall steepness on the amount of …

Ball Mill Crushing
Ball Mill Crushing by tube-mills were first introduced into the crushing departments of cyanide plants when it was found that for crushing finer than 30-mesh other types of crushing machinery were not efficient. In order to crush with one pass, these mills were made 18 to 22 ft. (5.5 to 6.7 m.) in length. Pebbles were used as a grinding medium and the mills …

Hydrocyclone System Design
A cylinder-conical shape is the best design for a pulp feeding tank because it does not present inner edges with section changes that may cause unwanted sedimentation of solids. Although this design is the most appropriate, in large-volume pumping such as in closed grinding circuits, the prismatic design is more suitable (Fig. 10.1).
