The changing face of aggregate mining

What has become more evident than ever is that the country’s mining landscape is changing at a rapid pace with aggregate and sand mining operations required to adapt and meet future challenges head- on. This interview with Aspasa director Nico Pienaar looks at some of these challenges and how these can be solved to ensure that the industry remains buoyant and success- ful in the years ahead. 34 AfriSam cements KZN presence 35 Cat’s new-generation track-type tractor 37 Remanufacturer capacity is key 38 Customised screens from Joest 39 Telsmith jaw crushers prove their worth PLANT and EQUIPMENT SOLUTIONS

With only a few years to go before celebrat- ing its own centenary, PPC De Hoek on the N7 just outside Piketberg in the Western Cape, is an impressive operation. Its his- tory dates back to 1919 when the Hermon Piquetberg Lime Company discovered limestone. The De Hoek operation became the fourth cement factory in South Africa with cement from its plant going into many early projects in Cape Town. 4 Futurist calls for faster African integration 5 Crushing specialist earns global award 6 Corobrik upbeat on building sector 7 New GM for Lafarge 9 Experience needed to up blasting skills AROUND THE INDUSTRY

This paper, published in the Journal of the South African Institute of Mining and Metallurgy (SAIMM), outlines the poten- tial beneficiation opportunities of marble mining by the Griekwastad community in the Northern Cape Province. It looks at the necessity of skills transfer and calls for funding in terms of equipment, health and safety education, and a more effective way of marketing the marble found in the area. The recent acquisition of Trio Engineered Products by TheWeir Group provides impor- tant opportunities and advantages for both southern African distributor Pilot Crushtec International and TheWeir Group in terms of additional product and market opportuni- ties. The article looks at the reasons for this acquisition with comment from the leaders of both companies who are exploring other synergies between the two businesses. 30 Trio acquisition adds value to sand and aggregate sector
