Co-introduction of ancyrocephalid monogeneans on their invasive host, the largemouth bass, Micropterus salmoides (Lacepéde, 1802) in South Africa
(Elsevier, 2017)Largemouth bass, Micropterus salmoides (Lacepéde, 1802) were sampled from three provinces (Eastern Cape EC, North West NWP and KwaZulu-Natal KZN) in South Africa to assess for parasite diversity and community composition. ... -
Co-operatives as a development mechanism to support job creation and sustainable waste management in South Africa
(Springer, 2017)South Africa, as with most African countries, is facing the reality of limited economic growth, high levels of poverty and increasing unemployment. At the same time, waste generation is growing, especially in urban centres ... -
Co-pyrolysis of coal and raw/torrefied biomass: a review on chemistry, kinetics and implementation
(Elsevier, 2021)Thermochemical conversion via co-pyrolysis has the potential to be an efficient route for converting biomass to bio-energy and bio-refinery products. In this review, the implementation of co-pyrolysis of torrefied biomass ... -
Co-sputtered PtxPdyAlz thin film electrocatalysts for the production of hydrogen via SO2(aq) electro-oxidation
(Springer, 2016)A co-sputtered PtxPdyAlz ternary system was investigated for potential use as anode catalyst for the electro-oxidation of aqueous sulphur dioxide (SO2), a key reaction in the hybrid sulphur (HyS) process for splitting water ... -
CO2 reactivity of briquettes derived from discard inertinite-rich Highveld coal using lignosulphonate and resin as binders
(SAIMM, 2019)South African collieries generate approximately 31 Mt of fine and ultrafine coal annually, with the majority of the ultrafine fraction discarded in slurry ponds and underground workings. Use can be made of this energy ... -
Coagulation/flocculation potential of polyaluminium chloride and bentonite clay tested in the removal of methyl red and crystal violet
(Springer, 2017)This study investigated the influence of the physico-chemical properties of methyl red (MR) and crystal violet (CV) on their removal by bentonite clay and polyaluminium chloride (PACl). Different dosages of bentonite clay, ... -
Coal and coal ash characteristics to understand mineral transformations and slag formation
(Elsevier, 2009)A knowledge of the composition and structure of minerals in coal is necessary in order to understand the mineral transformations and agglomerate or slag formation during combustion or gasification. Coal ash fusibility ... -
Coal char temperature profile estimation using optical reflectance for a commercial-scale Sasol-Lurgi FBDB gasifier
(Elsevier, 2008)In the Sasol-Lurgi fixed-bed dry-bottom (FBDB) gasifier the temperature in the combustion zone should not exceed the melting point of the ash-forming minerals, causing them to melt/flow and agglomerate. Sintering of ash ... -

Coal cleaning residues and Fe-minerals implications
(Springer, 2011)In the present investigation, a study was undertaken to understand the origin of Fe-minerals presents in Brazilian coal mining and to understand the environmental implication and the chemical heterogeneity in the study ... -

Coal particle and bed physical transformational behaviour after thermochemical conversion in a fixed bed
(Elsevier, 2016)This paper examines the physical transformational behaviour that coal particles and the bed structure undergo in a fixed bed reactor. The transient overfeed configuration is used with feed gas entering from the bottom of ... -
Coal particle chemical transformational behaviour after thermochemical conversion in a fixed bed
(Elsevier, 2016)This paper examines the chemical transformational behaviour that coal particles undergo during conversion in deep packed beds, typically found in industrial combustion and gasification operations. Experiments were performed ... -
Coal power plant wastewater treatment by thermal and membrane technologies
(Wiley, 2019)Abstract This chapter contains sections titled: Introduction -- Mineral Scale Formation -- Scale Formation Mechanisms -- Scale Inhibition Mechanisms -- Characteristics of Anti‐Scaling Agents -- Principles of ... -
Coal product moisture control using stockpiles
(Springer, 2016)The moisture content of product coal is a major factor influencing the efficiency of downstream coal utilization processes. Product stockpiles are often used as a control measure to regulate the moisture content of the ... -
Coal reactivity and selection for solid-based pre-reduction of sponge iron
(Taylor & Francis, 2020)Solid-based direct reduction of iron ore requires the reductant coal to have a suitable CO2 reactivity to achieve optimum pre-reduction within a rotary kiln. The CO2 reactivity is affected by numerous factors including ... -
