纳米银粉制备

1.主要矿物有辉银矿(主要组分硫化银)、角银矿等。除从上述矿物可以炼出银外，电解精炼铜也可回收银，采用电解精炼法得纯银。工业生产采用电解法，即以金属银为原料，溶解于硝酸，配成电解液组成为：含Aｇ50 g/L，hn0.33～10g/L，加入电解槽进行电解。电解液温度约45 ℃，槽电压为2.5 V，阴极电流密度2.5～2.7 A／cm2。经电解精炼，制得高纯银粉成品。

超细银粉制法：以硝酸银溶液为原料，经还原法制得。

2.汞齐法的工艺原理是，把磨细的银矿石用食盐进行处理，若为硫化物矿时，则需要进行焙烧,将得到的氯化银与汞一起碾磨使生成汞齐，然后用蒸馏法除去汞而得到银。此法仅适用于处理纯银矿，目前很少用。

3.氰化法.此法是从纯银矿中提取银的主要方法，特别适用于氯化物矿。

其工艺原理是：将磨细的银矿石用稀的氰化钠溶液进行处理，银便进入溶液，硫化物矿溶解较慢，需要有适当过量的氰离子存在；或将硫化物矿预先氧化焙烧处理，它们才能溶解。用氰化法处理天然银（元素态）时，则需要鼓入空气，才能使其进行反应。将溶液过滤并除去空气，在碱性溶液中，用细粒状或片状锌或铝处理溶液，便得到金属银。从上述反应可知，铝能够直接使氰化物再生，但是所生成的锌氰配合物对银仍然是一个有效的提取剂，因此在整个过程中氰化物并不损失

4.浮选熔炼法。当银作为铜(或铅)硫化物矿石的一个组分存在时，银往往是作为精炼铅和铜的副产品而被提取出来。

（1）从铅块中提取银

从铅块中提取银的方法主要有Parkes法和Pattinson法。

a-Parkes法这是一种除去铅中银的常用方法，由于银和锌比银和铅具有较强的亲合力，因此它在熔融锌中的溶解度远比在熔融铅中的大。故在熔融的含银铅里加入足够量的锌，将发生如下反应，并随温度不同，结晶析出各种银锌合金。

Ag+αZnAgZnα

这种银锌合金在温度低于其熔点时，仅微溶于以锌饱和的铅中，于是在熔融铅的表面则形成银锌合金硬皮。取出硬皮挤压掉其中的大部分铅，并用蒸馏法除掉锌，再进一步用烤砵冶金法分离铅，便可得到纯银。

b-Pattinson法当融化的含银铅冷却到它的凝固点时，纯铅晶体首先凝固下来，而银及其杂质仍为熔融状态，把晶体移去，然后再加入含银的粗铅，进行熔融，冷却和移去结晶出来的铅，如此重复循环，最后便得到了富集了银的铅，它再经烤砵冶金法提取银。这一方法比较陈旧，现已逐渐被电解精炼铅时回收银的方法所取代。

(2)从铜中提取银

当铜矿或其富集物熔炼为冰铜时，所有原来存在的金和银也都进入冰铜中，当冰铜还原为金属铜时，银和金也与铜在一起。为了从铜中提取金和银，现在一般采用的是电解精炼铜时，从阳极泥中回收银的方法。在阳极泥中，银的含量较高，为了从阳极泥中回收银，首先应除去铜。由于阳极泥中有相当数量的硒和碲，故需将阳极泥在250～500℃焙烧，使铜成氧化铜，硒和碲变为二氧化物，然后用50%的硫酸处理除去铜；若铜以金属存在于阳极泥中，则毋需焙烧，可直接用硫酸处理。将除去铜的阳极泥置于转炉中并加热到1200℃，使其中的铅、铋和锑进入熔渣，然后吹入氧气，使砷和剩余的锑氧化与二氧化硒(或碲)一起挥发，最后再加入Na2CO3和NaNO3使余下的硒和碲形成亚硝酸钠和亚碲酸钠。由上所得银的纯度一般为97%～98%，这种粗银可用电解法精练成为纯银。

采用电解法。以金属银为原料，用硝酸溶解后，加入电解槽中进行电解。经电解精制后得到高纯银粉成品。
