Late 15th and early 16th century mining techniques, De re metallica It is impossible to know the exact date that humans first began to mine gold, but some of the oldest known gold artifacts were found in the Varna Necropolis in Bulgaria.The graves of the necropolis were built between 4700 and 4200 BC, indicating that gold mining could be at least 7000 years old.
Mining Wikipedia
OverviewMining techniquesHistoryMine development and life cycleMachinesProcessingEnvironmental effectsMining industryMining techniques can be divided into two common excavation types: surface mining and sub-surface (underground) mining. Today, surface mining is much more common, and produces, for example, 85% of minerals (excluding petroleum and natural gas) in the United States, including 98% of metallic ores. Targets are divided into two general categories of materials: placer deposits, consisting of valuable minerals contained within river gravels, beach sands, and other unconsolidated materials; and lode dep

Meanwhile, opinions have diverse expressions which bring along research challenges. Both of the practical demands and research challenges make opinion mining an active research area in recent years. In this paper, we present a review of Natural Language Processing (NLP) techniques for opinion mining. First, we introduce general NLP techniques
Zinc Mining and Processing: Everything you Need to Know
In the 18th century, it was discovered that sphalerite, or zinc sulfide, could be smelted into brass, resulting in the first patented techniques. Since then, the zinc industry has progressed to the current zinc mining process and production methods used today. The Basics of Zinc Mining and Processing
Gold Processing Methods & Gold Ore Extraction
Of all the methods of extracting gold & processing it from its ore, I used a few to evaluate two principal flowsheets in this case study. The flowsheets utilized operations that involved flotation, cyanidation and gravity concentration. Tests that mirror each of these unit operations were utilized to evaluate the principal flowsheets. This page offers a comparative review of gold recovery
