Safely executing drill and blast operations in cooperation with ongoing operations and ground support activities is critical in keeping construction projects on schedule. Construction sites are busy places, with many activities happening concurrently and sometimes sharing the same space. Orica's experienced engineers have developed …
Evolution of MINING TOOLS
Furthermore, the 19th century saw the emergence of new drilling technologies. The rock drill was a game-changer, enabling miners to bore deep into the Earth's surface for extraction. Additionally, the stamp mill revolutionized ore processing by mechanizing the crushing and grinding process, increasing efficiency and productivity.
methods of concentration of different ores
Iron ore - Wikipedia. Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel—98% of the mined iron ore is used to make steel. Indeed, it has been argued that iron ore is "more integral to the global economy than any other commodity, except perhaps oil".
Blastability and Ore Grade Assessment from Drill …
Blasting performance is influenced by mechanical and structural properties of the rock, on one side, and blast design parameters on the other. This paper describes a new methodology to assess rock mass quality from drill-monitoring data to guide blasting in open pit operations. Principal component analysis has been used to combine …
Raise bore drilling: mining South Africa's heart of gold
Raise bore drilling. A raise borer is a machine used in underground mining operations to bore a circular hole between one level and another, lower level, effectively removing the need to conduct risky and wasteful blast excavations using explosives.

Reverse Circulation (RC) Drilling | Geology for Investors
RC drilling works by blasting air down an outer drill pipe using a high performance air compressor at the surface. An air-driven hammer at the end of the drill stem pounds a tungsten -iron drill bit against the rock, pulverising and breaking fragments away. The drill bit, stem and pipe continuously rotate as the rock is being hammered.

How to Drill Into Cast Iron | Hunker
The recommended maximum drilling speed for soft cast iron is 150 surface feet per minute (SFM). This value is related to drill revolutions per minute (RPM) by the formula: RPM = SFM x 3.82/drill bit diameter. If you're drilling a 1/2-inch hole, then, the maximum drill speed should be 1,146 rpm, which is about midrange on most portable drills.
