Oil and Gas Production Wastewater: Soil Contamination and Pollution Prevention
Applied and Environmental Soil Science, Volume 2016, Issue 1, 2016., 2016 During oil and natural gas production, so‐called “produced water” comprises the largest byproduct stream. In addition, many oil and gas operations are augmented via injection of hydraulic fracturing (HF) fluids into the formation. Both produced water and HF fluids may contain hundreds of individual chemicals, some known to be detrimental to public ...

Application of hydrocyclones for recovery of fine gold from placer material [PDF]
, 1982 Alaska and other gold areas have seen a sharp resurgence of placer mining in the last few years. Mines using sluice boxes usually recover gold down to 100 mesh, but recovery of gold finer than this size is a function of particle shape factor, sluice box ...

Macromolecular Theory and Simulations, Volume 34, Issue 3, May 2025.A centrifugal technique for separating molten polymer blends is investigated computationally. In a rotating cylinder, the components of mixtures of LDPE (Low‐Density Poly(Ethylene)) and PET (Poly(Ethylene) Terephthalate) are separated due to centrifugal forces due to the different component densities.
