Read MoreLead is easily extracted from its ores; prehistoric people in Western Asia knew of it. Galena is a principal ore of lead which often bears silver. Interest in silver helped initiate widespread extraction and use of lead in ancient Rome. Lead production declined after the fall of Rome and did not reach comparable levels until the Industrial

Read More18/12/20160183;32;In many places, silver ore is often found in combination with other ores containing other commercially viable minerals such as copper, lead or gold. When silver is a byproduct of processing these other minerals then a different method has to be used to extract the silver ore. For example is silver is found in ore containing zinc a method known as the Parkes Process is used to mine the
Read MoreThe primary ore is galena or Lead sulphite PbS. This is unstable, and on prolonged exposure to the atmosphere it oxidizes into the minerals cerussite PbCO3 and anglesite PbSO4. Lead ores are usually associated with other metals, particularly silver which can be mined at the same time and zinc, which can cause problems during smelting.
Read MoreHow to extract silver ore from lead is one of the most common crushers on the crushing market. The machine is widely used in mining, building materials, chemical, metallurgical and other industries, and is suitable for primary and secondary crushing. The compressive strength of all types of minerals and rocks is much lower than 320 MPa. According to the hardness of the fractured material, the
Read MoreAlthough some silver bearing ores contain silver as their largest metal value, virtually none has silver as its main constituent. A typical ore might contain 0.085 percent silver, 0.5 percent lead, 0.5 percent copper, and 0.3 percent antimony.
Read MoreMost of the silver produced today is a byproduct of mining copper, lead, and zinc. The silver occurs within the ores of these metals in one of two ways 1) substituting for one of the metal ions within the ore mineral's atomic structure; or, 2) occurring as an inclusion
Read MoreAccording to Hodder, the first undoubted indication of the existence of silver lead ore was made in 1838, on a section [295] belonging to Mr. Osmond Gilles,5 but several different accounts have been given of the discovery. The first mention of ore having been found in the Mount Lofty Ranges was contained in a letter from Marmaduke Laurimer, a Cornish settler in South Australia, to his

Read MoreSilver production in South Australia commenced in 1841 as a by product of smelting lead ore from Australias first metal mine at Glen Osmond, an eastern suburb of Adelaide. In 2001, the state produced 27,502 kg of silver solely from the world class Olympic Dam CuUAuAg mine. The Pasminco Ltd smelter at Port Pirie is the worlds largest integrated PbZn producer and third largest
Read More6/11/20190183;32;Silver, as well as zinc and lead, is extracted from the ore using grinding, sequential flotation and leaching techniques to produce high grade lead and zinc concentrates with a high silver content. Canningtons is estimated to contain a total mineral resource of 55Mt at 184g/t silver from the underground sulphide and 30Mt at 98g/t silver from the open cut sulphide.

Read MoreGalena, also called lead glance, is the natural mineral form of lead(II) sulfide (PbS). 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. It is often associated with the minerals sphalerite, calcite and fluorite.

Read MoreSilver has been known since ancient times. Silver is mentioned in the Book of Genesis, and slag heaps found in Asia Minor and on the islands of the Aegean Sea indicate that silver was being separated from lead as early as the 4th millennium BC. The silver mines at Laurium were very rich and helped provide a currency for the economy of Ancient Athens. It involved mining the ore in underground galleries, washing the ores and smeltingit to produce the metal. Elaborate washing tables still exist at the site using rain w
