The extraction of alumina from bauxite is significantly impacted by the silica content of the ore — specifically the presence of silica in kaolinite (Al2Si2O5(OH)4). This is because traditional bauxite-beneficiation methods, such as washing, flotation and particle-size separation, also typically…
Construction is planned for a pilot plant that will demonstrate a modular electrochemical technology for extracting rare-earth elements (REEs) and nickel from industrial wastes, such as coal ash. The startup Blueshift (Boston, Mass.; www.buildblueshift.com) recently announced venture capital funds that…
Glucose is a key pillar in producing bio-based alternatives to conventional chemicals, but finding industrially viable, non-food-competitive sources for glucose has proven challenging, due to the difficulty in obtaining glucose from hemicellulosic materials, such as woody biomass, in a cost…
The Flexim Fluxus/PIOX 731 Series (photo) is a new range of non-intrusive, clamp-on ultrasonic flowmeters designed to offer flexibility, convenience and availability. The nine models in the 731 Series feature high-performance volumetric and mass-flow sensing technologies and a robust, functional…
Efficient and sustainable recycling of lithium-ion batteries is a crucial element in electrifying transportation. Black mass is a mixture of cathode and anode materials remaining after disassembly and shredding of end-of-life lithium-ion batteries (LIBs). Many valuable materials, including lithium and…
Industries face significant emissions-reduction and decarbonization challenges, but there is a clear path forward through strategic adoption of process optimization and new technology integration The chemical process industries (CPI) and associated value chains are as diverse as the products they…
A new facility in Texas to manufacture high-purity graphene powder from acetylene has been announced by HydroGraph Clean Power Inc. (Vancouver, B.C.; www.hydrograph.com). At capacity, the facility will generate thousands of metric tons per year of sp2-bonded powdered graphene with…
Actuators are attached to the control mechanism of a valve to replace a manual lever or handle, and they control the position of a valve (open, closed or specific position) remotely and automatically. In industrial applications, numerous types of actuators…
Using the right tools, chemical manufacturers can make sustainable step changes, such as for emissions reductions, while also increasing operational efficiency and product yield The chemical process industries (CPI) are characterized by faithful devotion to tried-and-true procedures, yielding efficient production,…
This conveyor accommodates discharge heights up to 40 ft The Helix® flexible screw conveyor (photo) is designed to excel in multiple applications, from bulk material transport to precise batching and blending, effectively accommodating powders, granules and irregularly shaped materials. The…
