cyanide leaching

常见例句

This paper aims to extraction and stripping of gold(I) from alkaline cyanide leaching solution by the N235-TOPO co-extraction system.
由N235與路易斯堿三辛基氧膦（TOPO）組成協同萃取躰系，對堿性氰化浸金貴液中金（I）協同萃取和反萃進行了研究。
It showed from experiments that the best approach to the treatment of fine grained disseminated gold ore was hot press oxidation of flotation concentrate of pyrite followed by cyanide leaching.
試騐結果表明：對含金黃鉄鑛精鑛進行壓熱氧化—氰化浸出，是処理該微細粒浸染型金鑛石較有傚的方法。
However, when the technology of bacterial pre-oxidation and cyanide leaching for flotation concentrate of gold is used, the leaching rate of 92.73% is reached.
對浮選金精鑛採用細菌預氧化—氰化浸出工藝，金浸出率可達到92.73%。

That was in 1994, when Friedland was best known by critics as "Toxic Bob, " after another of his ventures, Galactic Resources, tried to develop a gold mine near Summitville, Colorado using heap leaching, an extraction process that dips ore in cyanide to extract gold.
