The Legal Framework of Mining Industry in
Part 1: Introduction Mining is one of the oldest industries in Malaysia and this may be traced back to the early 1820s following the arrival of Chinese immigrants in Perak. The mining industry has consistently played a vital with the extraction of natural copper ores in copper mines. There are three basic methods of copper ore extraction: open-pit, underground, and leaching mining. Open-pit mining is a dominating form on a global scale. Figure 6 presents the global trends in copper mining in 1900-2016. As we can notice, the output reached 20.2 Mt in 2016 and showedIOP Conference Series: Materials Science and

Minerals Special Issue : Recent Advances in Copper Ore Processing
Producers, however, are facing challenges due to falling head grades and more complex ore mineralogy. In this Special Issue, recent advances in copper ore processing and extraction are discussed, focusing on: innovations in hydrometallurgical, pyrometallurgical, electrometallurgical, and pre-concentration technologies; improving The ore is then ground finely before the copper-bearing sulfide minerals are concentrated by a flotation process which separates the grains of ore mineral from the waste material, or gangue. Depending on the type of copper bearing minerals in the ore and the treatment processes used, the concentrate typically contains between 25 and 30% Copper Geoscience Australia

Copper processing Ores, Refining, Smelting Britannica
Principal forms in which copper ores are found include native copper, porphyry copper, massive deposits, and mixed ores. Native copper is simply the metal found unadulterated in nature. Occasionally copper is still found in its native form, but more frequently it is mixed with other minerals, some of which may have value themselves. The amount of copper in Mu et al. reported a process for synchronous extraction of nickel and copper from a mixed oxide-sulfide nickel ore in a low-temperature roasting system. In this process, sodium sulfate was used as an additive for improving the extraction of nickel by converting into Na-pyrosulfate, and more than 97% of nickel could be extracted after Comprehensive Review on Metallurgical Upgradation

Chemical Composition Data of the Main Stages of Copper
The mining industry has faced significant challenges to maintaining copper production technically, economically, and environmentally viable. Some of the major limitations that must be overcome in the coming years are the copper ore grade decline due to its intense exploitation, the increasing requirements for environmental protection, and 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 A Review of the Cyanidation Treatment of Copper-Gold Ores
