The NG Mining Africa Summit will bring together decision makers from across Africa to meet with solution providers who are actively looking to target this exciting growth market.
An HDPE geomembrane cap was selected for the closure of a 50 Ha Tailings storage facility in Western Australia. A 1000 year design life for the geomembrane was targeted to meet the stringent environmental and longevity requirement of the project. To maximize the resistance to surface oxidation and the initiation of stress cracking, the material was specified with significantly higher stress cracking resistance, oxidative induction times, oven (thermal) aging resistance, and UV resistance, than the GRI.GM13 standard specification. A comprehensive Manufacturing Quality Assurance (MQA) program of plant audits, material sampling, and laboratory testing was implemented. Stress cracking and oven aging results required some special consideration. A careful investigation, detailed analyses and implementation of stringent MQA program resulted in a material that met the requirements of all parties to the project prior to shipping from North America to Australia.
