Process Of Mining In Veladero Gold Mine Argentina

The Veladero gold mine is one of the largest gold mines in Argentina, and in the world. It is located 189 miles/305 km northwest of San Juan, at a height between 4000 and 4850 meters above sea level and located in the San Juan province of Argentina, immediately to the south of the Pascua-Lama property, Veladero gold mine in the highly prospective Frontera district.

The Veladero mine property contains several large deposits of gold and silver mineralisation in altered, silicified volcanic rock, and various types of silicified breccia. Main-stage mineralisation is superimposed on the Miocene volcanic vent complex of diatreme breccias, associated pyroclastic rocks, flow domes, and porphyry intrusions 

Process of mining in Veladero gold mine Argentina is a conventional mining open-pit operation where ore is crushed by a two-stage crushing process with drilling and blasting of ore and waste. Mineral rock transported and carried by a conventional truck  with shovel operation and transported via overland conveyor and trucks to the leach pad area.

Step By Step Copper Smelting Process In Palabora Mines

      Pyrometallurgy, or smelting, usually used in the smelting process of copper ore with sulfide and iron sulfide minerals. The concentrate is dried and fed into a furnace. The minerals are partially oxidized and melted, resulting in segregated layers.

Matte coating refers to a mixture of the iron sulfide-copper sinks to the bottom. The slag, which refers to the remaining impurities, floats on top of the matte. The slag is discarded on site or sold as railroad ballast and sand blasting grit. Sulfur dioxide gases are also collected and made into sulfuric acid for use in hydrometallurgical leaching (discussed below) or sold off-site.
