Processing and Disposal of Minerals Industry Wastes ‘03
Falmouth, Cornwall, U.K, 18-20 June 2003

PDMIW '03 was held at the Falmouth Beach Resort Hotel, in Falmouth. This was another successful conference organized by Minerals Engineering International (MEI) in one of the most remote but beautiful areas of mainland Britain. It was the first conference dealing with environmental issues and attracted around 50 delegates from 16 countries. Over 70 papers were submitted and 41 of high quality were selected for presentation.

MEI has a very close association with Elsevier Science in the production of Minerals Engineering journal and the principal aim of the MEI Conferences is to produce high quality scientific papers for publication in Minerals Engineering.

The papers presented were organized in five technical sessions, namely tailings disposal, coal wastes, effluent treatment, acid mine drainage and processing of wastes.

The tailings disposal session included the papers by P. Newman, M. Hodgson and E. Rosselot on “The disposal of tailings and minewater sludge using Geotextile dewatering techniques”, A. Cadden, P. Newman, R. Verburg and M. Fordham on “New developments in surface paste disposal of mine wastes”, M. Dillon and R. White on “Tailings storage at Lisheen Mine, Ireland”, A.W.L. Dudeney, I.I. Tarasova and P. Tyrologou on “Co-utilisation of mineral and biological wastes in mine site restoration”, and M. Benzaazoua, S. Ouellet, M. Fall, B. Bussière and T. Belem on “Contribution to understanding the mechanism of cemented paste backfill hardening”.

The coal waste session included the papers by B. Radloff, M. Kirsten and R. Anderson on “Wallerawang Colliery coal tailings briquetting project”, P. Bankowski, L. Zou and R. Hodges on “Using inorganic polymer to reduce leach rates of metals from brown coal fly ash”, A. Molina and C. Poole on “A comparative study using two methods to produce zeolites from fly ash” and M. Zilberchmidt, M. Shpirt, K. Komnitsas and I. Paspaliaris on “Thermal processing of sulfur containing coal wastes”.

The effluent treatment session included the papers by K. Komnitsas, G. Bartzas and I. Paspaliaris on “Efficiency of limestone and red mud barriers: laboratory column studies”, A. Esau, J.W. Coetzee and F.W. Petersen on “The removal of heavy metals from metallurgical waste using biosorption”, R.A. Kleiv, K.L. Sandvik and M. Thornhill on “Adsorptive removal of copper using mechanically activated olivine”, A.N. Ajah et al on “Molybdenum removal and recovery from wastewater produced by a styrene monomer plant”, M. Iqbal and R.G.J. Edyvean on “Production of fungal biomass immobilized loofa sponge (FBILS)-disc biosorbent for the removal of heavy metal ions from aqueous solution” and C.J.Hallett, R.H. Coulton, J.Dolan and C.Marsden on “The Wheal Jane minewater treatment plant - performance to date”.

The acid mine drainage session included the papers by S. Santos, R. Machado, M.J.N. Correia and J.R. Carvalho on “Treatment of acid mining waters”, M. Benzaazoua, P. Marion, I. Picquet and B. Bussiere on “The use of pastefill as a solidification and stabilization process for the control of acid mine drainage”, M. Thornhill, R.A. Kleiv, K.L. Sandvik, B. Jerkeng, and E.R. Iversen on “Development of a modelling tool for the prediction of pollution transport from subaqueous sulphide tailings deposits” and K. Komnitsas, D. Kolitsa and I. Paspaliaris on “Efficiency of reactive materials for decontamination of acid leachates”.

Finally, the processing of wastes session included the papers by S. Brochot, M.V. Durance, J. Villeneuve and M. Mugabi on “Modelling of the bioleaching of sulphide ores: application for the simulation of the bioleaching/gravity section of the Kasese Cobalt Company Ltd reprocessing plant”, N. Fraunholcz on “Separation of waste plastics by froth flotation- a review”, H. El-Shall and P. Zhang on “Process for dewatering and utilization of mining wastes”, C.J. Mitchell, D.J. Harrison, H. Robinson and N. Ghazireh on “Minerals from waste-recent BGS and Tarmac experience in finding uses for mine and quarry waste”, S. Kelebek, S. Yoruk and B. Davis on “Characterization of basic oxygen furnace dust and zinc removal by acid leaching”, E. Sonmez, H. Ozdag, S. Koca and H. Ipek on “Beneficiation of colemanite concentrates from fine wastes”, and D. Read, B. Rabey, F.P. Glasser and A. Street on “Implementation of a strategy for managing radioactive scale in the china clay industry”.

Before the presentation of the selected papers, short presentations of twelve poster papers was organized. It has to be underlined that the poster session was very interesting and initiated many lively discussions throughout the conference.

The interaction and socializing of the delegates in a relaxed atmosphere was vital and contributed to the success of the conference. Discussions in the conference room, during coffee breaks and lunches and exchange of information on a number of scientific issues provided an initial informal peer-review of the papers and according to my personal view initiated future research efforts.

As a common practice for all MEI conferences, no proceedings were issued. Instead, all participants received the draft papers in a CD-ROM. The authors who presented the papers have been asked to submit the full papers within a month after the conference. All papers will be then double refereed, revised if necessary and, if accepted, published early next year in a special issue of Minerals Engineering entitled “Processing and Disposal of Minerals Industry Wastes”.

Last but not least the assistance provided by the conference secretariat throughout the conference is greatly acknowledged. Barry Wills’ guided coastal path walk and the Gala Dinner were some of the things that delegates will remember.
