TAILING RECLAMATION= OASIS = CLOSURE

The reclamation of mica flakes from tailing disposal using gravity separators and flotation

A sample from the small-sized tailing pile of an Iranian mica processing plant was subjected to a series of mica recovery experiments. Mineralogical and microscopic investigations indicated that the dominant mica mineral was phlogopite which was accompanied by plagioclase feldspars. Before beneficiation studies, the particle size distribution of the representative sample was obtained, and the s...

Oasis.

prioritizing the reclamation criteria during mines closure (golgohar, sangan, chadormalu iron mines)

introduction development of natural resources and mining activities are prerequisite for economic and industrial growth in many countries. in many cases, such mining areas lie within residential or agricultural lands or natural habitats intensifying the contradiction between land use and environmental protection. different components of mining activities including exploration, extraction and pr...

DNA tailing without terminal transferase.

Tailing of DNA with terminal transferase is a technically demanding, but essential step in full-length cDNA cloning procedures*•^. It is also an essential step of a poly(dA) affinity labelling technique, which has been used to select families of partial restriction fragments on oligo(dT)cellulose^•*. In order to bypass the need for transferase in the latter technique, we made a simple modificat...
