Application of survival theory in Mining industry

Abstract

The paper deals with an application of survival theory in mineral processing industry. We consider the problem of maximizing copper recovery and determine the best operating conditions based on survival theory. The survival of the system reduces to a problem of maximizing a radius of a sphere inscribed into a polyhedral set defined by the linear regression equations for a flotation process. To demonstrate the effectiveness of the proposed approach, we present a case study for the rougher flotation process of copper-molybdenum ores performed at the Erdenet Mining Corporation(Mongolia).

Optimal Control Sphere Packing Problem

“…The sphere packing problem is one of the oldest problems in mathematics and finds many applications in science and technology [1][2][3][4][5][6][7][8]. Recently, new applications of sphere packing problem have been appeared in mining industry [13], finance and economics [16]. In general, the sphere packing problems are reduced to difficult nonconvex optimization problems which cannot be handled effectively by analytical approaches.…”

A sphere packing approach to break even and profitability analysis

“…This problem has important applications in science and technology. Recently, new applications of sphere packing theory have been appeared in finance [5] and mining industry [17]. Also, an attempt to apply of sphere packing approach to CVP anaylsis with respect to volume has been made in [21].…”
