Ancient techniques used for the mining of raw materials. Sufficient supplies of metallic and mineral raw materials required systematic mining, since only gold was found in large enough amounts in washes of brooks and rivers to make panning worthwhile. Other metals usually occurred as chemical components of ore minerals, which were found in Mineral deposits have supplied useful and valuable material for human consumption long before they became objects of scientific curiosity or commercial exploitation (Misra 2000).In fact, the earliest human interest in rocks and beautifully coloured minerals was probably because of the easy accessibility at the surface, e.g. of the earthy Ancient Ore Deposits SpringerLink

Gold of the Pharaohs 6000 years of gold mining in Egypt
The gold occurrences described in this study are located in the Precambrian basement of Egypt and Sudan, also called the Arabian–Nubian shield (ANS), which extends from the river Nile eastwards towards the Arabian Peninsula. To the south, the continuation of the ANS is the Mozambique Belt (Vail, 1988). It is generally accepted that the ANSAbstract. Of the 60 metals and semimetals that are known today, only 9 were known from antiquity to the Roman period, namely copper, gold, silver, lead, tin, iron antimony, mercury and zinc. The semimetal arsenic, which occurs regularly in ancient artefacts from the beginning of extractive metallurgy, was unknown, as was nickel.Making Metals: Ancient Metallurgical Processes SpringerLink

Chapter 3 Ancient Egyptian Metallurgy History of Applied
Martin Odler. Metallurgy is the science of separating metals from their ores, and it developed quite recently, considering the length of human history. Ancient Egyptians were neither the inventors of metallurgy, nor the most innovative in its development. [1] Yet metals, especially gold, had a very important place in their culture, and theyThe ancient gold accumulation cycle ends with the formation of the so-called “paleoplacer” deposits (Viljoen et al., 1970; Hutchison, 1987). The large gap (1.8–0.8 Ga) in gold ore formation is caused by the long existence of a stable cratonic regime (the Columbia and Rodinia supercontinents) on the Earth, emphasizing the uniqueness ofGold Deposits in the Earth’s History Geology of Ore Deposits

The golden ore had to be crushed and afterwards processed with panning and sluicing technique so that gold could be extracted gold from the rock. In the ores of Zlaté Hory gold is mostly bounded to pyrite (about 70%) and this is the reason why the major parts of a gravitational concentrate, extracted by using this technology, had to be processed in Gold deposits and occurrences are spread over a large number of sites which covered by Precambrian the basement rocks in the Eastern Desert of Egypt, and the gold exploration and mining activities had been districted since ancient times.
