摘　　要：泡沫塑料吸附法(下称泡塑吸附法)是新开展起来的一种泡沫塑料为载体吸附多种金属元素的找矿方法,是金矿化探中行之有效的手段。本文将从一些实际找矿效果来说明泡塑吸附法找金的发展前景。泡塑吸附法及其应用效果(一)方法原理金在白然界中以分散状态存在为其特征,可分为原生金和表生金两部分,而在各种类型金矿上方及其周围土壤中,金几乎均以自然金和极少量的金络合物、金有机化合物等方式存在,并且能溶于王水和碱性氰化物中。土壤中微量金和王水化学反应形成氯金酸反应式为:In application of adsoption method of foamed plastic to searching for gold,aqua regia iacts as solvent and foamed plastic acts as adsorbent for extracting poly-phase state gold in thesoil.By using this method,the tangible geological results have been obtained.This method has a universal applicable value in searching for various metal deposits,The spot analysis is suitable for large quantities of geochemical samples.
