Considerations of mineralogy and permeability testing of selected Sand/Bentonite mixes by Makgekgenene, Boné

“…In the context of permeability, the grain size distribution, all round pressure, compaction, hydraulic gradient, quantity and distribution of bentonite within a mix contribute immensely towards the coefficient of permeability of any sand/bentonite mix. …”

Use of grape pomace as a fine aggregate in concrete by Adam, Christopher

“…The stalks were omitted from the pomace and only the seeds and skins were oven dried and ground from a particle size of 3 to 5 mm down to 0.6 to 2.4 mm. Fine aggregate in concrete aids the binding of cement, water, and coarse aggregate, increasing workability, limiting shrinkage, and reducing the cement content required to fill the voids between the coarse aggregate. …”

An investigation into the precipitation of Fe(III) oxyhydroxides in lime neutralization processes by Mangunda, Cledwyn Tawanda

“…The initial studies on the dewatering behaviour indicated that the [Fe(III)] in the feed influenced (to varying extents) the dewatering trend of the precipitation product, via particle size, particle size distribution (PSD), surface charge, morphology and structure. …”

Assessment and modelling of chromium release in minerals processing waste deposits by Petersen, Joachim

“…The minerals processing industry is by far the largest generator of mineral solid wastes, which are commonly stored in large scale landfill deposits. The potential environmental impact of these is directly linked to the time-dependent process of leachate generation within these deposits. …”

Design optimization of gas-to-liquid biosludge management systems by Mostafa, Rana

“…The simulation-sub-model predicts the daily final sludge amounts collected from the DB and transported to the landfill (LF) for disposal. The cost and optimization sub-model generates the alternative designs that are sized by the design sub-model and calculates the capital and operating costs based on the results of the simulation sub-model for each design alternative. …”
