Best grinding method. | Fandom
Best grinding method. Mine all the ore in water cavern. This will give you 3080 and will take 3-5 minutes. Then stand on the cheese spot (protruding rock) and snipe the 2 bears near you, the 2 bison, and the one bear on the other side of the water in bear claw with a sharps or spitfire. This gives 2-3k and will take 5-10 minutes depending on luck.

The crushed ore is then transported to the mill site for crushing, grinding, classification and concentration. The second stage, grinding, is a wet operation which requires initial flotation and water to make a slurry. The hydrocyclone operates between each grinding operation to classify the type of particles: fine or coarse (Long et al., 1998).

Mining The ore is removed from the ground in either open pit or underground mines. Underground – sinking a vertical shaft into the earth to reach the copper ore and driving horizontal tunnels into the ore. Open-pit – 90% of ore is mined using the open pit method. Ores near the surface can be quarried after removal of the surface layers. The ore
2. Mining Methods - Copper
Blasting and grinding equipment are used to accomplish this task. Open pit mining is a technique used to extract copper ore near the earth's surface. Open pit mining is the most widely used technique of mining copper today. It is accomplished by creating and using benches or terraces to gradually reach deeper under the earth's surface.

Why mining is done so deep in the ground? Underground mining is used for ores that are deep in Earth's surface. For deep ore deposits, it can be too expensive to remove all of the rocks above the ore. These methods are more expensive than surface mining because tunnels are made in the rock so that miners and equipment can get to the ore.
