Authors: Denhere, R.; Zvarivadza, T.; Sengani, F. Abstract: The mining industry in Zimbabwe presents an opportunity for economic growth and development as the country is a host to at least sixty economic minerals. Resource based development through linkages can lessen dependence on non-renewables and lead to industrialisation and diversification. This paper focuses on challenges and recommendations on mineral beneficiation and value addition. Mineral beneficiation and value addition promote job creation and retain more natural resource wealth as prices of finished products are less susceptible to price fluctuations. Beneficiation and value addition form one of the four pillars in Zimbabwe working towards economic recovery and diversification hence the importance of analysing challenges and recommendations to fully implement beneficiation strategy. Challenges associated with beneficiation include skills and power shortages, limited access to international markets, inadequate infrastructure and working capital constraints. The government of Zimbabwe can successfully implement the beneficiation strategy through finalisation and implementation of the country’s mineral policy. The government can embark on investing in skills and human development, carrying out viability of constructing PGM refineries and the viability of revamping closed beneficiation plants. Policy unpredictability and inappropriate policies hinder foreign investment. Policy consistence and political commitment are crucial for leveraging mineral resources for economic growth and development. 2019-04-01T00:00:00Z Denhere, R. Zvarivadza, T.

Abstract: Previous studies have reported that the major function of mesh (welded or diamond) is to maintain the load bearing capacity of the rock mass along the excavation boundaries. Rock bolts are mostly used to control the overall stability of the excavation through arching, keying or reinforcement actions, while a mesh is installed to retain small to large pieces of loose rocks. Further studies have pointed out that the mesh support is more effective in building up hangingwall pressure to inhibit further slabbing at the vicinity of the bolt pattern. A detailed study on static performance tests on the welded mesh with the configuration of 5.6 mm diameter wires spaced at 100 mm centres and the mesh sheet of 1.5 m wide and 3.4 m long was done. The test was followed by the breaking strength/ tensile tests on the mesh strands to identify the maximum load that each mesh strand can withstand. For static tests, mesh samples were bolted onto the test frame in series with load cell and it was installed between the upper and lower platens of the 8 896 kN Mohr & Federhaff compression testing machine. The increase in load was applied gradually in perpendicular to the plane of the mesh through 500 mm long line loading interface across the wires. This loading was performed until the specimen failure took place. On the other hand, tensile tests of each strand of the mesh were performed through pulling the steel welded mesh strand until it breaks. Based on the three static tests results, it was noted that welded mesh can withstand several forces at a maximum force of 27 kN, 35.2 kN and 37 kN with the maximum displacement of 420 mm throughout the tests. On the other hand, tensile tests/ breaking strength results have shown that mesh strands can withstand maximum load ranging between 10.35 kN to 13.85 kN. It was then concluded that welded mesh has the ability to withstand the maximum load of 37 kN, with the displacement of 410 mm, while mesh strand was found to break at maximum of 13.85 kN. 2019-04-01T00:00:00Z Sengani, F.

Abstract: Preconditioning techniques have been applied in rockburst prone mines around the world in order to redistribute the stress peak further into the solid region ahead of the mining face by eradicating the strain energy in the asperities of the mining-induced fractures. The intention of this paper is to review the application of preconditioning practice, specifically in South African hard rock mines and outline gap knowledge revolving around this study. The results of the study have shown that there are two types of preconditioning techniques (face perpendicular and parallel). However, only face perpendicular preconditioning practice has been documented to have been successfully implemented in both conventional (non-mechanised) and fully mechanised gold mines. In this paper, it is maintained that although this technique has been reported to have been successfully implemented in many cases, there are still unanswered questions concerning this technique, therefore it is argued that this practice cannot be made an international practice before this gap knowledge are well addressed. 2019-04-01T00:00:00Z Sengani, F.

Abstract: Excellence in a mining venture is indicated by a competent marketing plan in place. The supplier needs comprehensive knowledge of the principles underlying the marketing of their particular commodity. Marketing saves to make known a product to the consumers. Failure to do that results in a wasted mining and processing of a mineral commodity effort. This paper seeks to bring to light the assortment of issues to be addressed in the marketing of iron ore. It delves deeper into the four main pillars of marketing which are the 4Ps: Pricing of the commodity, Place where the customer is located if we are to reach them, Product detail and the Promotion of the product. Iron ore marketing is somewhat different from high value per unit minerals like precious metals and stones. It has a lower unit value and is sold in bulk, requiring a superb knowledge of establishing marketing infrastructure like competent wide roads, port facilities, railway lines and the railway wagons. The pricing mechanism is also different. One of the main goals of marketing (customer satisfaction and care) is also covered in this paper. 2019-04-01T00:00:00Z Zvarivadza, T. Sengani, F.
