Based on the material composition, the geochemical nature, palynoflora study and agedating it is assumed safely that the loess is aeolian deposit mostly originating from the de-serts in Tarim Basin under fairly dry climate of steppe type, and overspreaded piled mainlyfrom the last glaciation maximum through Holocene period, which might be related to thetime when the Taklimakan deserts were extensively formed. The occurrence of the frequentmodern wind-blown dust precipitation along the south margin of Tarim appears to be themodern loess accumulation, meaning that the loess kept depositing strongly since the lastglaciation maximum. The palynofloras indicate that the biological environment associatedwith the loess deposition is quite similar with the modem one at the northern slope ofKunlun Mts. It is supposed that the modern lower general circulation, related to the loessformation, was completely set up probably in the last glaciation maximum. On the aridbackground occurred some moist fluctuations. Around 7 000 to 5 000 a.B.P. was a aromi-nent humid oscillation when thick soil developed ana snail.

With the development of gold science and technology, more and more gold mines emPloy CIP Process, zinc dust Precipitation and heaP leaching to recover gold.Due to gold extraction by cyanide Process results in discharge of hazardous substance in great quantity, the close attention is increasingly Paid to its environmental Pollution.Despite there are many alternative treatment Processes, such as alkali-chlorine Process, acidification Process, So2 Process, electro chemical Process, natural Purification Process etc,most gold mines in China are far in excess of discharge standard of Pollutant in high treatment and Production cost.Consequently,to find out a way to treat waste water at low cost and high efficiency is a matter of great urgency. This PaPer made an overview of the technology to recover cyanide from cyanide Pulp with distinct economic and social benefit

随着黄金科学技术的发展,采用氰化炭浆(浸)法、锌丝(粉)置换法及堆浸法生产黄金的矿山越来越多,由于氰化法提金排放的有害物质较多,污染危害极大,引起人们的关注。尽管处理方法较多(碱氯法,酸化法、二氧化硫法、电化学法、自然净化法等),对污水进行了处理,但多数地区仍超过规定的排放标准,而且处理费用较高,增加了生产成本,目前已成为人们十分关心的问题。寻求方法简单、成本低、效果好又实用的污水处理方法是当前急待研究的新课题。 本文着重介绍从氰化矿浆回路中回收氰化物的新工艺、新方法,具有明显的经济效果和社会效益。

The characteristics of B.O.F.'s dust precipitation water adopted by the steel-works of Shuicheng Iron & Steel Corporation are illustrated in this paper. According to its characteristics, the comprehensive technical measures are taken to convert the precipitation water with heavy encrustation into non-encrusting water, therefore, B.O.F.'s dust precipitation water can be recycled and reused. The outstanding economic and social effects can be achieved.
