     Macroscopical physical encapsulation ability of pollutants in the solidified sludge was studied by flexible-wall permeability test. The results show that bentonite can greatly reduce the permeability of solidified sludge, and improves its monolith, therefore reduces the release of pollutants from sludge.
     采用柔性壁渗透试验对固化体中污染物的宏观物理包裹进行了研究,结果表明膨润土的掺入降低了污泥固化体的渗透性,提高了固化体的宏观物理完整性从而降低了污染物的溶出能力。

The mineralogical. change of Huang Jin Dong refractory gold concentrate in the roasting Process wasstudied in this paper and the reasons of gold remaining in the residue were analyzed. The experimental resultsand supposition showed that the structure and composition of calcine had a great effect on the gold leachingrate. Porous structure is of benefit to the leaching of gold. Pyrrhotite as an intermediate phase in theoxidation process of pyrite and arsenopyrite is of benefit to the submicron gold particles to borne gathering.If the arsenic and sulphur content in the calcine is high the gold leaching rate will be low. The arsenic con- tent of the calcine has a strong influence on the eventUal recovery rate of gold by cyanidation. Gold exists inthe residue in the form of nature and is covered in the dense hematite particles,Moreover the ores being cov-ered in gangue lead gold particles remaining in the residue.

本文研究焙烧过程中黄金洞难浸金矿发生的矿物学变化,并推测浸金残渣中金残留的原因.通过实验和推测分析,得知焙砂的结构和组成对浸金有很大的影响.疏松多孔的结构有利于浸金.在焙烧过程中,最好能使黄铁矿和砷黄铁矿通过中间生成磁黄铁矿阶段,以利于亚微金粒的聚结长大.焙砂中砷、硫含量高,浸金率低.残渣含金与焙砂中砷的含量有很密切的关系.浸出残渣中的金主要以自然金存在,物理包裹在焙砂颗粒内致密氧化铁孔隙壁和氧化铁膜中,另外脉石中包裹有矿物,矿物中夹杂着脉石均有可能使残渣中残留金.

It has been found that the colour of red iron oxides in ceramics is affected by sintering temperature and the compositions of the ceramics.The reasons for these remain unclear and therefore have been studied here.Particularly,the stability of red iron oxides,the reactivity with other oxides,and silica wrapping effect have been studied.The results show that the colour of the red iron oxides in ceramics is affected mainly by four factors:(1)sintering temperature:the red iron oxide itself is unstable at high temperature,and tends to become black Fe 3O 4 by releasing O 2;(2)some active components in ceramics;these components,such as CaO etc.,would react with the red iron oxide and produce non-red compounds;(3)some other active components in ceramics;these components,such as MgO etc.,would also react with the red iron oxide but produce red-like compounds;(4)stable components:these components,such as Al 2O 3,SiO 2,can not react with the red iron oxides.Of the four factors above,the forth factor improves the colour stability of the red iron oxides in ceramics through physical wrapping;the first and second factors would deteriorate the colour of the red iron oxides in ceramics;the influence of the third factor is very limited.

本文考察了烧成温度、陶瓷坯体中常见氧化物 ,以及二氧化硅包裹对铁红呈色稳定性的影响。结果表明 ,陶瓷坯体中铁红的呈色主要受四种因素影响 :( 1 )温度 ,高温下铁红本身不稳定 ,易失氧而成黑色四氧化三铁 ,因此对呈色不利 ;( 2 )陶瓷坯体中某些活泼成分 (如氧化钙等 ) ,高温下易与铁红反应生成其它颜色的物质 ,因此对呈色不利 ;( 3 )陶瓷坯体中另一些活泼成分 (如氧化镁等 ) ,高温下也易与铁红反应 ,但生成物较稳定且接近红色 ,因此对呈色影响不大 ;( 4)陶瓷坯体中稳定成分 (如二氧化硅等 ) ,在通常温度( 1 2 0 0℃ )下不与铁红反应 ,但对铁红起到了物理包裹作用 ,对呈色有利。这四个因素交叉影响 ,最终导致产品呈色既与温度有关 ,又与坯体组成有关。
