A new electrowinning process is being field-trialed at the Prieska copper-zinc mine operated by Orion Minerals Ltd. (Melbourne, Australia; www.orionminerals.com.au) in South Africa, which will enable the production of valuable products, including calcium, magnesium, iron and others, from contaminated mine…
LanzaTech Inc. (Chicago, Ill.; www.lanzatech.com) has developed a genetically engineered bacterium capable of converting carbon dioxide directly to ethylene, the most widely used chemical building block globally. The company has incorporated the engineered biocatalyst into a continuous process in a…
Li extraction A new technology is going to be introduced at the Schlumberger NeoLith Energy direct lithium-extraction (DLE) project in Clayton Valley, Nev. Developed by Gradiant Ventures (Boston, Mass.; www.gradiant.com), the technology enables high levels of lithium concentration (while simultaneously…
In late October, Metso Outotec Corp. (Helsinki, Finland; www.mogroup.com) introduced the DRI (direct reduced iron) Smelting Furnace to substitute blast furnaces used in iron- and steelmaking. The furnace was developed to tolerate high-slag volumes, which are problematic for a conventional…
Liberty Steel UK (LSUK; London; www.libertysteelgroup.com) has completed trials of ecoke — a sustainable new raw material that can replace anthracite, the main source of charge carbon used in the electric-arc furnace (EAF) of steelmaking, and reduce steel’s carbon footprint…
When scaling up new processes involving complex feedstocks, such as biomass, well-defined mixing is key. Guidelines presented here will help to efficiently move biomass hydrogenation reactions from the laboratory to commercial-scale operations One of the most promising pathways to biomass-based,…
Liquid-liquid extraction (LLE) is a separation technique that exploits differences in the relative solubility of compounds of interest (the solute) in two immiscible liquids — most often an aqueous phase and an organic solvent. This one-page reference reviews basic information…
Chlorum Solutions LLC (São Paulo, Brazil) will use thyssenkrupp nucera AG & Co. KG (Dortmund, Germany) technology for its next two chlor-alkali plants in Brazil. The company has ordered two skid mounted plants with BM2.7 electrolysis technology from the supplier…
Hollow silica particles (HSPs) are materials of interest for thermal insulation applications because of their very low thermal conductivity, but the particles pose health hazards and the powder is impractical to use, so scientists have been trying to incorporate HSPs…
Last month, Metso Outotec Corp. (Helsinki, Finland; www.mogroup.com) introduced NextGen Pelletizing — a visionary concept for the next generation of iron-ore pelletizing plants that strive to be carbon neutral and autonomous. According to the company, the combination of innovations —…
