CRUSHING, SCREENING AND RECLAMATION

REPLANT, REUSE and RECYCLE Waste and water

– Water, Sewage, Refuse and Recycling – Solutions for the Mining and Construction Industry.” This forum, she says, will bring together suppliers and consumers of innova- tive solutions and technologies in the areas of water, sewage, refuse and recycling. Crewe emphasises that water manage- ment is a critical focus area in Mining. “Water is the ultimate enabler of living and in Southern Africa we do not have high levels of water security. Added to that, we depend highly on shared fresh water resources, with two or more member States sharing more than 70% of these,” she says. “Mining and Construction companies can play a proac- tive part in addressing this risk.” Patrick Hulley, managing director of Wilo Pumps SA who will be exhibiting at IFAT Envi- ronmental Technology Forum Africa says, “It is absolutely crucial for companies to manage the available water resources effec- tively and to ensure that they participate in a well-defined water management strategy. Yet there is much room for improvement in the definition and implementation of such strategies, which are also a key factor in Corporate Social Responsibility.” He points out that some of the challenges within the Water sector in SADC include the increased demand for potable water, a lack of under- standing surrounding the consequences of not managing water resources effectively, a further lack of maintenance practices and a lag in new technology acceptance. Wilo has researched and developed numerous technologies that contribute to effective water management strategies. For example, an innovative Ceram Coating is a method of coating parts of a pump, which in turn reduces friction and raises pump efficiency. He notes a waste management example of a “highly efficient Solid Sepa- ration system, which allows for the more

Elaine Crewe, CEO of BAUMA CONEXPO AFRICA says, “There are some simple actions that can be taken over the life of a mine, which may be logistically and technologically complex, but it remains imperative for mining houses. > at the end of its production cycle, can have a monumental impact in land rehabilitation.” Kenmare Resources, an Irish company with a Moma Titanium Mine in Mozambique, for example initiated a simple yet effec- tive waste management activity of growing trees. Back in 2012, the company reported that it had doubled the capacity of its nursery, which had been constructed for the rehabilitation of its mined areas. It increased the type of plants being grown from six to 18 and twelve hectares of mined land were rehabilitated and prepared for handing back to the local government. In addition, three trial plots were established on the rehabilitation areas to determine the appro- priate soil fertility enhancement strategies to be used. “Mines should have recycling projects in play,” adds Crewe. “At this year’s BAUMA CONEXPO AFRICA we will showcase waste and water management by focusing on envi- ronmental technology through hosting IFAT Environmental Technology Forum Africa management in the mining sector may be considered to be costly by many and

BAUMA CONEXPO AFRICA BAUMA CONEXPO AFRICA, Interna- tional Trade Fair for Construction Machinery, Building Material Machines, Mining Machines and Construction Vehicles takes place between 15 and 18 September 2015, at the Johannes- burg Expo Centre (JEC). The premiere of Bauma Africa in September 2013 attracted 754 exhibitors from 38 coun- tries and 14 700 visitors from over 100 countries. Covering a total of 60 000 m 2 of exhibition space (40 100 m 2 net) this is the biggest event for the sector in Africa. mental and social impacts of a mine, both in the short and long term, need to be miti- gated against. As a resource rich continent, those with mines in Africa have a respon- sibility to protect, even nurture the local people and land within their operations. The good news is that there are technologies available through which to do this.” effective collection and transport of water and waste water to treatment plants which results in uptime of the operations to move waste water from and around cities and other areas.” Crewe concludes: “Any negative environ-
