Study on the Kinetics of Two-ores Leaching of Galena
方铅矿的两矿法浸出动力学研究
属类:行业术语-中文论文标题-
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。

The mineral galena is composed of lead sulfide. But when lead is found alone and not combined with another element, it is referred to as native lead.
方铅矿这种矿物就是由铅硫化物组成的。但如果铅以单元素形式构成物质而不与其它元素结合,便可称此种矿物为自然铅。

Cleavage occurs on planes where the atomic bonding forces are weakest; for example, galena cleaves parallel to all faces of a cube. Cleavage is described by its direction (as cubic, prismatic, basal)and by the ease with which it is produced. A perfect cleavage produces smooth, lustrous surfaces. Other degrees include distinct, imperfect, and difficult.
解理产生于结合力最弱的平面上,如方铅矿可以平行于立方体的所有晶面劈开。解理是按其方向(如立方体解理、柱面解理、底面解理等)以及产生解理的难易程度来描述的。完全解理很容易产生光滑而有光泽的平面。其它等级依次为︰中等解理、不完全解理和极不完全解理。

Sulfur: Nonmetallic chemical element, chemical symbol S, atomic number 16. It is very reactive but occurs native in deposits, as well as combined in various ores (e.g., pyrite, galena , cinnabar); in coal, petroleum, and natural gas; and in the water in sulfur springs.
硫:非金属化学元素,化学符号S,原子序数16。硫元素非常活泼,但可以以天然硫的形式存在,也以化合物的形式构成各种矿石(如黄铁矿、方铅矿、辰砂)、煤炭、石油和天然气都含数量不等的硫化合物;有的矿泉水也含硫。

Other uses are in storage batteries, ammunition, and low-melting-point alloys (e.g., solder, pewter)and as shielding against sound, vibrations, and radiation. Lead is rarely found free in nature; its major ore is the sulfide galena (PbS).
其它用途有制造蓄电池、枪弹和低熔点的合金(如焊料和白镴),以及隔离声音、振动和辐射的保护装置。铅在自然界中很少呈游离态,主要存在硫化物和方铅矿中。

1.A bluish, grey, or black mineral of metallic appearance, consisting of lead sulphide. It is the chief ore of lead.
‘This karsting provides highly permeable rocks in which the sulphide minerals sphalerite and _galena_ represent the valuable mineralization.’
‘The main ore minerals are _galena_ , chalcopyrite, sphalerite, and tetrahedrite that are associated with quartz and barite gangue.’
