再次浸出

The larger particles contained in the pulverized product which has advanced into the elutriation device 2 are precipitated at the bottom portion of the elutriation device 2 and sucked by the sand pump 6 to also be returned to the tower shell 1 wherein the larger particles are again subjected to pulverization and leaching.

较大的颗粒在煤粉产品已经迈入了淘洗装置 2 沉淀在底层部分的淘洗装置 2 则是将由砂泵 6 也应该归还给塔壳里一大颗粒再次遭受为了粉碎和浸出。

The effects, such as the acidity of leaching system, the temperature and the concentration of the sodium chloride, on oxidation and leaching of copper-bearing gold ores were analyzed. The results show that the sequence of sulfide ores oxidized and dissolved are pyrrhotite firstly, sulphide secondly, then chalcopyrite, pyrite lastly.

结果表明：硫化矿的氧化溶解首先是磁黄铁矿，其次是铜的次生硫化矿，再次是黄铜矿，最后是黄铁矿；载金黄铜矿的氧化首先是铁从黄铜矿的晶格中氧化溶解出来，生成中间产物CuS2和CuS；较高的酸度和氯化钠浓度有利于单质硫的生成、三价铁的水解和铜的浸出，进而有利于金浸出率的提高。

The method comprises the steps that the molybdenum bearing spent catalyst is roasted and comminuted, then the molybdenum bearing spent catalyst is leach and filter by adopting alkaline solution bearing ammonia, ammonium bicarbonate and oxyful, and the secondary roasting and leaching are performed to the solids after filtration, the twice leaching solution is acidified and the aluminum is precipitated out, then is acidified continuously to precipitate out the molybdenum in the form of molybdic acid, the molybdic acid is dissolved by using ammonia water further, the pH value is adjusted again to obtain ammonium molybdate deposition, and the ammonium molybdate product is obtained after dryness.

将含钼废催化剂进行焙烧、粉碎，然后采用含氨、碳酸氢铵和双氧水的碱性溶液浸取并过滤，过滤后的固体物进行二次焙烧和浸取，两次浸取液酸化沉淀出铝，然后继续酸化将钼以钼酸形式沉淀出来，钼酸进一步用氨水溶解，再次调节pH值获得钼酸铵沉淀，干燥后得到钼酸铵产品。

But heavy metal in solidified sludge could be leached again because of Thiobacilli activity in the sludge.

污泥固化后能够降低重金属的浸出风险，但是污泥中硫杆菌的活动存在再次将重金属浸出的可能。

Larger particles are sucked from the receiver 8 into a sand pump 6 via a pipe 5 so as to be returned to the tower shell 1 wherein the larger particles are again subjected to pulverization and leaching.

较大颗粒则是将从接收机 8 成砂泵 6 透过管道 5 ，以归还给塔壳里一大颗粒再次遭到粉碎和浸出。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
