LIHIR GOLD LTDAnnual and Transition Report (foreign
May 07 2008 · Lihir mine ore is termed refractory meaning that conventional extraction of gold by cyanidation is not viable without pre-treatment. The Lihir operation s process plant incorporates a pressure oxidation pre-treatment step using autoclaves to release the gold. This in turn is followed by conventional cyanidation.

NUP pre-treatment partially protected mice in two models of acute septic shock. We concluded that NUP is anti-inflammatory by inhibiting the NF-κB pathway modulating cytokine production and ERK phosphorylation. A significant average survival rate (60 ) of LPS lethally-challenged mice was achieved by pre-treatment with NUP.
