1·A new wet-chemical method for producing metallic silver directly from silver sulfide was proposed.

提出了一种新的从硫化银直接制备金属银的湿化学方法。

2·The leaching solvents for the separation of silver sulfide and native silver were investigated in this test.

文中针对硫化矿物中硫化银与自然银的浸取溶剂及分离方法进行了探讨。

3·Thiourea in a sulfuric acid solution causes silver sulfide (silver tarnish) to revert to silver metal by an electrolytic action.

在硫酸溶液中硫脲会引起硫化银(氧化银)由电解行动恢复纯银色的金属。

4·Most silver ores in dispersive state exist in oxidation manganic minerals(62.79%), others exist in sulfide mineral(28.65%), and few or no silver chloride and natural silver.

大部分银以超显微分散态（硫化银占62.79%）存在，同时在少量的金属硫化物中也赋存着一部分银（占28.65%），角银矿和自然银极少。

5·The method that the gold concentrate adding sodium sulfide is roasted could effectually raised the recoveries of gold, silver and copper.

该方法是将金精矿加入硫化钠后进行焙烧预处理，可有效地提高金、银、铜的回收率。

6·Silver has the highest conductivity and thermal conductivity, but the low melting point, low hardness, easy to produce sulfide film.

银具有最高的导电率和导热率，但熔点低，硬度低，易产生硫化物膜。

7·The gold deposits in Uzbekistan may be divided into 4 industrial genetic types: gold quartz, gold sulfide quartz, gold sulfide and gold silver quartz types.

乌兹别克斯坦的内生金矿床主要有4个工业-成因类型：金石英型、金硫化物石英型、金硫化物型和金银石英型。

8·It was also found that, besides native silver, there existed coPPer-bearing argentite which seemed to be an alternation Product through the replacing of native silver by late-formed copper sulfide.

银矿物除自然银外，还见有后期铜的硫化物交代自然银形成的含铜辉银矿。

9·The results showed that active sulfide in jet fuel could induce silver strip corrosion. The main corrosion factor was elemental sulfur.

结果表明，活性硫化物会导致银片腐蚀，其主要因素是元素硫。

10·The contents, occurring state and geological characters of the associated gold and silver in the magmatic type of copper and nickel sulfide deposits in China are discussed in this paper.
