Water services in small towns in developing countries: at the tail end of development
The current lack of knowledge about small towns, the great diversity of such settlements and the pressure to ‘scale up’ interventions make it difficult for policy makers and practitioners to develop models which are suitable for these towns. Currently, principles and practices informing models for water services in urban and rural areas are applied in small towns without question. This paper highlights how these principles that are engrained in the sector, may be pernicious for expanding water services in small...
United States - Copper recovery (tailings processing) - Case Study
Country: United StatesMachinery: Copper/plastic recycling line, multiple-separation lineA big Guidetti line consisting of 4 refiners and separators with production up to 5 ton/h. It allows the recovery of all copper in tailings, coming from cables’ processing lines.Advantages:- Total copper recovery- Higher plastic purityInstalled in 2016, it is a benchmark for the American market and not only. One of its kind also for its dimensions, it is giving us great satisfactions.
Acid production potentials of massive sulfide minerals and lead–zinc mine tailings: a medium-term ...
Weathering of sulfide minerals is a principal source of acid generation. To determine acid-forming potentials of sulfide-bearing materials, two basic approaches named static and kinetic tests are available. Static tests are short-term, and easily undertaken within a few days and in a laboratory. In contrast, kinetic tests are long-term procedures and mostly carried out on site. In this study, experiments were conducted over a medium-term period of 2 months, not as short as static tests and also not as long as...
Cut-Off Wall - Abandoned Mine Tailings Pond - Case Study
ProblemAt an abandoned mine in the Yukon Territory, mining for both Gold and Zinc took place until the mid 1950`s, with the processing of the ore taking place on the banks of an adjacent lake. Processing methods resulted in the creation of a large mine tailings pond that had high concentrations of iron, arsenic, zinc and lead. Spring runoff and summer rainfall then infiltrated through the pond resulting in contamination of the lake with heavy metals. The lake is a primary source of drinking water and the prevention...
