Galena, also called lead glance, is the natural mineral form of lead(II) sulfide. It is the most important ore of lead and an important source of silver. Galena is one of the most abundant and widely distributed sulfide minerals. It crystallizes in the cubic crystal system often showing octahedral forms.
A crystal detector is an obsolete electronic component in some early 20th century radio receivers that used a piece of crystalline mineral as a detector (demodulator) to rectify the alternating current radio signal to extract the audio modulation which produced the sound in the earphones. It was the first type of semiconductor diode, and one of the first semiconductor electronic devices.

It is extracted from galena (lead sulphide). Lead is a comparatively soft, malleable metal that can be fabricated, bossed, carved and filed with ease, but its most useful properties are its low melting point, 327°C, and the ease with which it can be cast.
bench-scale experiments using 20- to 200-g samples of PbS. Large-scale leaching, using 10 kg PbS and 75 L H2SiF6 solution, was conducted in a 100-L reactor described previously. Lead Electrowinning. Electrolyte was prepared from the PbS leachates, which contained 80 to 100 g/L Pb as PbSiF6 and 90 to 100 g/L free H2SiF6.
Galena value: Some mines produce more revenue from the silver content of their galena than from the lead content. Assume that we have a mine that produces argentiferous galena with an average composition of 86% lead, 13% sulfur and just 1% silver (as shown in the diagram on the left).
Abstract: In this thesis,a series of oxidation experiments on galena are conducted under different condition such as pH is 2,temperature is 50°C and 25°C.After the experiment is completed,The rate constant,reaction order,reaction reaction rate and energy of activation are also analyzed and computed.The effects of temperature and oxidized medium on lead ore oxidation speed were studied.

The proposed study provides the results of the chemical, morphological, and kinetic analysis of the lead extraction from galena concentrate derived from the Koni Mansur polymetallic deposits for the first time. The experimental results are compared with the lead-containing galena mineral from the well-known Balya deposit in Turkey. 2. Experimental
So the addition results (we obtained a more aerated bath which attached of lead compensated for the insuicient lead in the ore and to the scoriier); it did not help the operation and actually played the role of the lead normally derived from the galena: hindered it. herefore, we did not continue to experiment to lower the smelting temperature ...
The established lead-zinc ore flotation processing scheme is to add zinc sulphate (ZnSO4) to the grind to control metal ion activation (sphalerite depression). ... The flotation tailing is the zinc concentrate. If the silver is associated with the galena, the silver reports to the lead concentrate. While pyrite is …

Galena Group. Galena is the primary ore mineral of lead. Worked for its lead content as early as 3000 BC, it is found in ore veins with sphalerite, pyrite, chalcopyrite, tennantite-tetrahedrite, etc. and in skarns, as well as in sedimentary rocks where it may replace carbonate beds or be deposited in pore spaces.
Assaying ores can also involve we did not assay) is 14.8wt% lead. a preliminary fusion in a triangular crucible, especially for copper ores; as we limited our experiments to galena, this he gangue minerals are silica, limestone or barite in varying step was unnecessary.

Galena (lead sulfide) is the mineral with highest quantity (86%) of lead. More than half of the lead produced is used for manufacturing automobile batteries. Lead is alloyed with copper and antimony to make it harder and resistant to acid. Interestingly, there is no lead in 'lead pencils'.
Lead can be prepared from galena [lead(II) sulfide] by first heating with oxygen to form lead(II) oxide and sulfur dioxide. Heating the metal oxide with more galena forms the metal and more sulfur dioxide. Write a balanced equation for the overall reaction by adding the balanced equations for the two steps.

Greenside Mine (sometimes referred to as Greenside Lead Mine) was a successful lead mine in the Lake District of England. Between 1825 and 1961 the mine produced 156,000 long tons (159,000 tonnes) of lead and 1,600,000 ounces (45 tonnes) of silver, from around 2 million tons of ore. During the 1940s it was the largest producer of lead ore in the UK.
