As evident in Fig. 1.2, the world's production of usable (processed) iron ore has increased from about 970 million tons in 2000 to 2.45 billion tons in 2019. Australia is the largest iron ore producing country, producing approximately 919 million tons of usable ore in 2019, equivalent to about 37% of the world's iron ore production.

Mining consists of several unit operations linked to each other, and the performance of the initial stages (drilling, charging and blasting) pre-conditions the downstream unit operations in the production cycle (Ghosh 2017).For an efficient blasting, it is essential to have a well-defined characterization of the rock mass; automatization in …

Blast hole drilling is a method of drilling used to clear out large amounts of the earth and make the minerals below easier to access. It involves the drilling of holes into the earth. Explosive charges are then placed into each hole and detonated. After the explosion, the broken material is cleared and, if the drilling and blasting occurred ...

A typical surface mine can produce up to 150,000 tons of ore every day. Sometimes whole mountains (or tops of mountains) are removed through surface mining processes. The most predominant surface mining methods used to extract iron ore are open-pit and open-cut methods. These two methods are considered to be the least expensive extraction ...

This value is connected with your drill revolutions per minute through the simple formula: RPM=SFM x 3.82/ drill bit diameter. This means that if you are drilling a ½ in hole, the max drill speed you should aim for is 1,146 rpm. This is the midrange for most cordless and corded drills. Cut this speed in half for hard cast iron or if you are ...

Use a sharp Drill bit. A dull bit will just cause the cast iron to chip and break, making it more difficult to drill through. Go slowly at first. Start with a small hole and then gradually increase the size of the hole as you drill. Then keep the area well lubricated.
