Processing, smelting and refining gold World Gold

2021-7-8  The Miller process uses gaseous chlorine to extract impurities when gold is at melting point; impurities separate into a layer on the surface of the molten purified gold. The Miller process is rapid and simple, but it produces gold of only about 99.5 percent purity. The Wohlwill process increases purity to about 99.99 percent by electrolysis.

Recovery and purification of plant-made recombinant

Recently, non-chromatographic purification methods, such as aqueous two-phase partitioning and membrane filtration, have been evaluated as low-cost purification alternatives to packed-bed adsorption. This paper reviews seed, leafy, and bioreactor-based platforms, highlights strategies for the primary recovery and purification of recombinant proteins, and compares process economics between systems.

Production and purification of recombinant DP1B silk

To develop a plant platform for production of recombinant silk-like protein, two plant-optimized DP1B genes were synthesized to mimic spidroin 1. DP1B-8P encodes for a 64 kD DP1B silk-like protein and DP1B-16P for a 127 kD DP1B silk-like protein. Both genes have been introduced into Arabidopsis for leaf-based production driven by the 35S promoter
