On the other hand, the number of studies focused on the impacts of mining and mineral processing on the environment and human health in Africa have increased significantly during the last decade. However, these studies tended to be concentrated on the effects of mining and mineral processing at national levels and

Figure 2 is the sieve analysis plot of Itakpe iron ore showing the economic liberation size. The economic liberation is -425 +300 µm. The knowledge of economic liberation of minerals have always been useful in mineral processing plants because it saves time and energy.

and the required degree of processing and end use. Developing countries dispose of abundant industrial resources, and could derive greater economic benefits from them than they do now. Per capita consumption of industrial mineral products continues to grow in developed countries and part of this demand could be met by exports from developing

Mining plays a vital role in the economic development of many countries. Historically this has been the case in many parts of the developed world, and while mineral development is an important factor for economic growth it can also, if done responsibly, be a catalyst for social growth in developing countries.

processing cost is then equal to the value of the resulting mineral after processing minus the sales cost. Finding the OCOG is a bit more complicated because first, the opportunity cost of maintaining unexploited reserves has to be calculated, and then added to the processing cost. However, this value will automatically optimize the NPV and IRR.

cal processing." Fig. 2 summarizes the mineral processing flow and the transition to the refining stage (hydrometallurgy). The goal of mechanical processing is to produce individual particles by comminution of ore which has a complex material composition. To the extent possible, these in-

Introduction to Mineral Processing 5 3.0 Liberation and Comminution 3.1 Liberation In order to separate the minerals from gangue (the waste minerals), it is necessary to crush and grind the rock to unlock, or liberate, valuable minerals so that they are partially or fully exposed.

The objectives of this study is to gain an understanding of the following areas of social and economic development as per the requirements of the Mineral and Petroleum Resources Development Act (MPRDA), Act No. 28 of 2002:

In coal preparation wet processing is in preference to dry processing, wherever water resource is available. 3. Components of Mineral Beneficiation Technology Processing of mineral beneficiation is composed of a series of unit operations as illustrated in Figure 1 by a simple example. Raw ore, or 'run-of-mine ore', is received by

The question of transforming primary products for export, including local mineral processing has been addressed by successive development plans in African countries. Few projects have been realized so far. This study examines the potential impact of mineral processing activities on industry linkages and growth prospects for countries in Africa.
