CiteSeerX — MERCURY DISCHARGES FROM SMALL SCALE

Small scale gold mines in North Sulawesi alone emit approximately 64 tons of Hg per year to the environment, exceeding the 40 tons per year emitted from coal-fired power plants in the United States. Replacing Hg-amalgamation with gravity separation followed by vat cyanidation would bring about significant environmental benefits.

Small-scale Triton X-114 Extraction of Hydrophobic Proteins

Here we introduce a protocol for Triton X-114 extraction which we used in our recently-published paper (Taguchi et al., 2013). It is a versatile method to concentrate or partially purify hydrophobic proteins. The presented protocol is based on the protocol published by Bordier (Bordier, 1981) but more simplified and down-scaled for more small-scale and simpler use (Taguchi et al., 2013).Triton

The Mercury Problem in Artisanal and Small‐Scale Gold

Mercury‐dependent artisanal and small‐scale gold mining (ASGM) is the largest source of mercury pollution on Earth. In this practice, elemental mercury is used to extract gold from ore as an amalgam. The amalgam is typically isolated by hand and then heated—often with a torch or over a stove—to distill the mercury and isolate the gold.
