方铅矿

An effective procedure for the production of chromium yellow with nitric acid hydrolysis solution of Galena was studied.

应用方铅矿的硝酸酸解液可生产出多种铅产品，其中合成铅铬黄是比较便捷的一种。

Lead content in the crust is 0.0016%, however it is easily obtainable and is usually found in galena ore.

铅在地壳中的含量为0.0016%，主要矿石是方铅矿。

The mineral galena is composed of lead sulfide.

方铅矿这种矿物就是由铅硫化物组成的。

Lead is rarely found free in nature; its major ore is the sulfide galena.

铅在自然界中很少呈游离态，主要存在硫化物和方铅矿中。

One is a compound, the other an element, yet both galena and native lead are minerals.

方铅矿和自然铅，虽然一种是由化合物构成，另一种是由单元素构成，但它们二者都是矿物。

Experiments on dissolution kinetics of galena were performed in 1 mol/L NaCl solutions at ph 0.43-2.45 and 25-75℃.

本课题在25～75℃、pH=0.43～2.45的1mol/L NaCl溶液中进行了方铅矿的溶解动力学实验。

The sulfide mineral mainly consists of pyrite, and a small amount of pyrrhotite, galena and sphalerite.

硫化矿矿物主要为黄铁矿，其次为少量的磁黄铁矿、方铅矿、闪锌矿。

And some fabulous new samples of green Fluorite on Sphalerite and Galena from Naica, Mexico, which were collected some time this year - here Evan is holding one of the best examples of this new find.

还有一些新标本的如来自于墨西哥奈卡的闪锌矿和方铅矿上共生绿色萤石，这是今年的热门收藏，埃文在此次展会上最好的一批中淘到了一个。

These CRM's are for analysis of Crystal,Zinc sulfide and galena by microbean.

此类标样用于水晶、硫化锌和方铅矿的微束分析。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
