Post-mining Nutrient Depletion of Bauxite Overburdens in Jamaica: Storage Methods or Subsoil Dilutioe. Increasing the soil organic content during storage could be one corrective approach. However, it is far less costly to exercise greater care to apply more precise overburden removal and emplacement techniques initially, than it is to correct the results of top-soil contamination with sub-soil.

Dust Reduction in Bauxite Red Mud Waste using Carbonation, Gypsum & Flocculationighed. This submergence process was repeated. The first submergence produced 30- and 20 % w/w dust respectively from the 25- and 50 % phytogenic treatments, and 0 % dust from the non-phytogenic treatments. Submergence #2 released no clay (wet dust) particles from any sample. Finally, the same sample说不出 发表于 2025-3-25 13:31:49
Fragility and Bearing Capacity of Gray Shales in North-Eastern Jamaica After Landslips: Origins, andafter subsequent high-intensity bursts of rainfall. Rapid weathering of strong, hitherto un-weathered shale rocks was fast enough to have been measurable weekly (4 mm depth per week) after exposure by a landslip. Regular early morning rain showers followed by hot, dry afternoons caused frequent wet/occurrence 发表于 2025-3-25 16:41:46
Hydrocarbon-Contamination of Soils Around a Trinidadian Pitch Lake: Red Muds as a Resistance to Poteated soil implies blocking of hydraulic channels by inorganic particles. The high levels of Na. released in the Bayer beneficiation process dispersed and released fine <5 mµ clay particles from the non-gypsum-treated red muds. This suggests that the rapid movement of aqueous pollutants in such hydroBiofeedback 发表于 2025-3-25 22:42:12

Detoxification of Acid Drainage Using Inorganic pH Buffers in a Constant Flow Bioreactormollisol in 1:5 ratio (w/w) and the mixture placed on the sand in the column to occupy the column volume, except for a 10 cm wide space at the top of the column. An electrically powered peristaltic pump slowly pumped the AMD into the column from the bottom, until the top of the treatment material inironic 发表于 2025-3-26 10:33:38
Aggregation of Sodic Subsoils Using Gypsum and Decomposable Phyto-organics: Interactions and Implicaasses which exceeded 100 µm in diameter. The results of this study promise the use of gypsum as an ameliorant for sodic alkaline environments such as the red muds of bauxite mine-spoils. Where no organic matter had been added, it is concluded that the binding action of Ca. released in solution repla信任 发表于 2025-3-26 13:28:55
Structural Amelioration of Indurated Gypsum-Treated Bauxite Red Mud Tailings Using Bacterially Mediature of the newly formed phyto-organically treated gypsum-hardened RMW aggregates was also substantially improved over that of the controls, as a 3-fold increase in resistance to disintegration during wet sieving was exhibited by the phyto-organically treated samples. The increase in water infiltrat极小 发表于 2025-3-26 20:29:38
Erodibility of Unconsolidated Mine Wastes Under Simulated Rainfall and Hydraulic Forces After Organieness of the treatments was in the order (descending) of GM > SS = SSGM. For leachate residue material, the effectiveness of the treatments was in the order (descending) of GM = SSGM > SS. When SS was treated (as if it were a soil), the GM, and SSGM treatment combination yielded the most stables agg
