These porphyry gold–copper deposits of the Urals, which are still problematic in terms of geotectonic setting and ore-formation parameters, are associated with subvolcanic bodies and small intrusions of a small age range (382–374 Ma) for the Yubileinoe and Petropavlovsk deposits and 428 Ma for the Bereznyakovskoe porphyry gold–copper ...
Gold ores are usually associated with copper, zinc and silver. Cyanidation of gold ores presents many difficulties; hence, there is need to research ways to counteract the associated problems.1 One gold mine in Zimbabwe processes a gold ore of 1.53 g/t, rich in copper. The run of mine …
Globally, copper, silver, and gold orebody grades have been dropping, and the mineralogy surrounding them has become more diversified and complex. The cyanidation process for gold production has remained dominant for over 130 years because of its selectivity and feasibility in the mining industry. For this reason, the industry has been adjusting its methods for the …
A significant contemporary challenge for gold mining companies is to define economic process options for treating more complex ore bodies as the less refractory ores become depleted.
Nickel is one of Zimbabwe's principle metallurgical exports. It is processed to a very high level of purity and hence has a high value. The economics of nickel production can be difficult, as the selling value of nickel varies tremendously with time, from a low of US$ 3 900 per ton in late 1998 to US$ 10 100 per ton in May 2000, and to US$ 8 500 less than a year later.
The country boasts the second-largest platinum deposit and high-grade chromium ores in the world, with approximately 2.8 billion tons of PGM and 10 billion tons of chromium ore. Yet the country still remains amongst the poorest nations in the world, and exporting minerals from Zimbabwe is a dauting task.
For gold minerals, a commonly used leach solution is a cyanide solution, while for copper minerals, a leach solution containing sulfuric acid may be used. The leach solution seeps into the ore pile, reacting with the gold and copper minerals within it, and the gold and copper dissolve from the ore into the leach solution.
The Dalny Gold Mine is situated in the region of Mashonaland West, Zimbabwe. Within this mine, the mineralized ore consists of scheelite, pyrite, and sphalerite, while the waste material predominantly comprises quartz. The geological formation hosting the mineralization in this specific area is known as greenstone.

Keywords: ammoniacal cyanide leaching, pre-treatment, lead nitrate, copper-gold ore, gold . INTRODUCTION . Cyanidation process is extensively usedfor leaching of gold from ores since cyanide forms strong complexes with gold. In this process, some impurities such as copper and arsenic problems are present (Hayes and Corrans, 1992; Bas . et al
Precolonial mine workings existed on the Central African Copper Belt (Bisson, 1976) the copper-bearing geology of Zimbabwe (Summers, 1969; Swan, 2002), in eastern Botswana (Huffman et al., 1995), and northern South Africa (Van der Merwe & Scully, 1971).Brightly colored malachite and azurite ores likely drew attention to surface outcrops of the resources.
