Silver Gold Recovery Flotation Process - 911 Metallurgist

17/10/2016  Flotation follows ordinary standard methods, modified as may be necessary to bring up the precious metals in the concentrates where they will be of most value. Thus, in a lead-zinc ore, silver is more valuable in the lead than in the zinc concentrate. Similarly, in a copper or lead ore carrying gold associated with pyrite, it might be profitable to make an iron concentrate containing the gold. If the gold and silver

Copper Sulfide Flotation - 911 Metallurgist

13/04/2016  The above flowsheet is designed for the treatment by flotation of copper as chalcopyrite with gold and silver values. The ore, ranging from 60-65% silica, with pyrite, arsenopyrite, and calcite with 3 to 4% copper. This flowsheet, though simple, is adequate for tonnages of 100 to 500 tons or more per day, depending on the size of equipment selected. It can be readily expanded by duplicating units

Coins from Ethiopia – Numista

Ethiopia’s numismatic history was affected by the multitude of different currency influences that arose in the following years. The Birr had first been tied to the Italian Lire and then to the East African Shilling, during which time the subdivision became known as the Santeem, after the French Centime. These new conventions were formalised in 1976 when a new Birr coinage was released, still ...

Coins from Ethiopia – Numista

Ethiopian coins carry inscriptions in the Amharic language, using the Amharic alphabet. The Ethiopian numeric system also differs from the decimal system used in most countries, and the calendar also uses a different zero point, eight years earlier than the more common used AD/CE calendar. This can create confusion in the identification and precise dating of Ethiopian coinage. Currently ...

Optimisation of gold recovery by selective gold flotation ...

01/02/2001  The aim of the testwork was to optimise the free gold recovery by; (1) enhancing the copper and gold recovery into a copper concentrate and (2) floating the gold away from the copper sulphides and pyrite. The ore was crushed to -2 mm and ground in a stainless steel laboratory rod mill to a p80 of 106 ~tm for the flotation tests. At this size, a substantial proportion of the free gold is ...
