Algae constitutes roughly half of the Earth’s photosynthetic activity and undergirds the food chain for approximately 70% of the world’s biomass. With over 100,000 strains ranging from microscopic single-cellular organisms to seaweed species miles in length, algae would seem to hold almost unlimited potential for biochemical engineering and bio-refining applications. Though they have formed a...

Controlling particle size is critical in alumina processing, especially when alumina crystals are precipitated from Bayer liquor — a highly caustic solution where bauxite is dissolved to produce alumina. The ability to control the conditions of the precipitation process through online monitoring of particle size can improve production and quality. With this in mind, a group from CSIRO Minerals...
