B ides the tellurides mentioned above that are common in gold deposits, Te isalso seen in such rare minerals as hessite, Au2Te and, a variety of unnamed telluritesand tellurates that may be subdivided into Au-bearing and Au free minerals. Theformer includes AtteO3, Au2TeO4, AuTeO4; and the latter schieffinilite, Zn2Te3O8,H2Pb2Fe4[TeO4]9.7-12H2O that were found by the author and are yet to be furtherstudied for acceptance by IMA-CNMMN as potential new minerals.

除上述碲化物外，碲在本矿床形成罕见的碲银矿、Au2Te和种类繁多的未名碲化物、碲酸盐等含氧盐，含氧盐进一步可分为含 Au、不含Au，包括 AuTeO3、Au2TeO4、AuTeO4 等以及水硫碲铅石、Zn2Te3O8、H2Pb2Fe4［TeO4］9.7－12H2O等，后二种为待申报的新矿物。

A brittle silver-white metalloid element that is related to selenium and sulfur; it is used in alloys and as a semiconductor; occurs mainly as tellurides in ores of copper and nickel and silver and gold.

Most of thesete1lurites and tellurates in these deposits are found to be products of coeval oxidationof calaverite, altaite and sufides, by Which "refractory gold" of Au tellurides will bereleased as naive gold. Most native gold released through oxidation of tellurides,however, will be trapped in the telluraes or tellurites; or be combined by Te intellurites or tellurates, which prevent gold of hyPergene from secondaxy enrichmentunder the supergene oxidation environrnenis.

研究表明，这些碲含氧盐大多数为碲金矿、碲铅矿与硫化物共同氧化的产物，&难溶金&矿物在氧化条件下发生分解，一般释放出自然金；由于金要么以自然金形式被&捕获&于这些含氧盐，要么重新与碲形成Au－Te含氧盐，所以抑制了金的次生富集。

Moreover, the nanorods of cobalt tellurides and nick tellurides were successfully prepared.

并且制得了碲化钴和碲化镍一维纳米棒。

A brittle silver-white metalloid element that is related to selenium and sulfur; it is used in alloys and as a semiconductor; occurs mainly as tellurides in ores of copper and nickel and silver and gold.

一种脆的、银白色非金属元素，与硒和硫有关联，用于合金及作半导体，主要作为碲化物存在于铜、镍、银、金矿石中。注意，注意力集中

In early stage, suflides and selenides instead of tellurides were in focus, and little metal-metal interaction exists in these layered chalcogenides.

从结构特征看，已有的层状三组元硫族化合物中没有或少有金属-金属相互作用。

Nanocrystalline copper tellurides Cu〓Te〓 and Cu〓Te〓 have been successfully prepared in ethylenediamine and ethylenediamine with hydrazine hydrate system under high-intensity ultrasonic irradiation at room temperature respectively. Nanocrystalline silver tellurides Ag〓Te and Ag〓Te〓 have been successfully prepared in ethylenediamine and ethanol system under high-intensity ultrasonic irradiation at room temperature respectively.

在制备碲化铜时，在纯乙二胺体系超声辐射所制备的最终产物为Cu〓Te〓，而在加有水合肼的乙二胺中制得的产物为Cu〓Te〓；在制备碲化银时，在乙二胺体系制备的产物为Ag〓Te，而在乙醇体系制备的产物为Ag〓Te〓。

In gold ores, Te presents as tellurides of Au, Ag, Pb inassociation with native gold, occurring in surfaces or/and fissures of galena, pyriteand quartz minerals. Therefore, Te and the "refractory gold" are worth being extractedfrom these abundant tellurides.

碲在矿石内主要以AU、Ag、Pb 碲化物与含Ag自然金共生，它们在局部的矿物量相近，并分布于方铅矿、黄铁矿、石英表面和裂隙，其中的&难溶金&与碲本身都具有回收价值。
