Cradle to grave Kumba takes health care to the people B efore 2015, people from the communities around Postmasburg in the Northern Cape travelled 30km or more — often on foot — to get primary health care. Thanks to a major investment in the health care infrastructure by Kumba Iron Ore, Anglo American’s iron ore business unit, mobile clinics now take health care to the communities. A newly upgraded Postmasburg medical complex boasts a high-tech trauma care unit, which accommodates and stabilises patients before they are moved to more advanced medical facilities. Bags to de-sludge S the existing ones to make additional space available for waste. Traditional methods of waste containment, which usually require large amounts of space, stringent environmental permits, and frequent dredging, are normally unaffordable to municipalities,” explains Johnny Oriokot, geotechnical engineer at Fibertex SA. “A feasible solution needed to be found to dispose of extracted material through the desludging process, which is not restricted by budget constraints and the limited space available at existing wastewater facilities. “The use of geotextile dewatering bags is recognised globally as the most efficient and economical method to achieve the required desludging process, to improve the functionality and safety of wastewater treatment works.” Fibertex geobags, manufactured from UV-stabilised woven polypropylene (PP) geotextile materials, are incorporated in the desludging process in wastewater treatment — the process used to convert wastewater into an effluent that can be returned to the water cycle with minimal environmental impact. Solid particles (sludge) are then separated from the effluent and transported to a designated safe disposal site or stored in a tailings storage facility at the wastewater treatment plant. everal measures to remove sludge from site have been implemented in various projects around the world. One of these involve using Fibertex geotextile bags (or geobags). Geobags are used on desludging wastewater projects and have some advantages over conventional methods, which are often unaffordable to authorities and contractors with limited budgets. The benefits of using geobags for sludge removal include ease of operation, efficient retention of solids, compliance with environmental regulations, and cost optimisation. A further advantage is that this dewatering system is passive and does not require constant monitoring and maintenance of equipment. The filtration properties of geotextiles — which are effective in retaining the fine-grained materials found in sewage sludge while allowing the water to filter through — make these materials suitable in desludging wastewater ponds. The effluent that passes through the woven fabric can then be transferred to a designated safe disposal site, given that it meets the regulations set by the Department of Water Affairs (Policy and Strategy for Groundwater Quality Management in South Africa). “When wastewater treatment ponds reach their capacity, the options available are to either build new facilities or to empty These Fibertex geobags are filled with processed mine waste. www.miningmirror.co.za Strikes and the economy A ccording to research, the right to strike is a delicate balance between the power of firms and the rights of employees and is considered a sign of a healthy democracy. Independent labour expert Suleyman Alley says there are seven key causes of labour unrest: health hazards in the workplace; excessive working hours; low wages; demand for leave with pay; discrimination; inadequate working tools; and aggressive behaviour of managers towards employees. “Strikes and labour unrest have marked negative impacts on the employees themselves, the employers and their stakeholders, the government, consumers, and the economy,” says Jacki Condon, managing director of Apache Security Services. “These actions create economic uncertainty, especially as the global media continues to share details, images, and videos of violence, damage to property, and ferocious clashes between strikers and security,” Condon continues. Strike action results in low productivity and a reduction in profits. Labour law expert Ivan Israelstam says that the employer is likely to lose money due to delayed service to clients or lost production time. “The employees will lose their pay due to the ‘no work, no pay’ principle. If the strikers are dismissed, they will lose their livelihoods altogether,” he says. This year alone, Eskom, Prasa, various manufacturing plants, Sasol, and the South African Post Office, to name but a few, have faced crippling strikes. Condon argues that there are more immediate consequences to consider than loss of income. “As the socio-economic issues continue to affect South Africans across the board, tensions are constantly rising,” states Condon. “Businesses must protect themselves, their assets, business property, and their non-striking employees from violence and intimidation.” Condon believes that this requires the deft hand of well-trained and highly qualified close-protection operatives. These operatives provide not only protection, but video evidence as well, ensuring those responsible for damage can be held to account. “The key is to create a strategic partnership with a reliable security provider. Plans must be put into place to protect businesses against vandalism, physical assault, property invasion, and intimidation during labour unrest,” concludes Condon. FEBRUARY 2019 MINING MIRROR [45]
