Mine Tailings

15 12 2010  Hazardous Properties Toxic chemicals used to extract the valuable materials from the ore such as the cyanide used in gold mining remain in the tailings at the end of the process and may leach out into ground water Rock may naturally contain dangerous chemicals such as arsenic and mercury which leach into water much more readily after rock has been ground up and exposed to the wind and

A discussion on the measurement of grinding media wear

01 07 2016  The grinding media may be the ore itself autogenous grinding bars balls or cylpebs or even the ore itself together with a small amount of balls semi autogenous grinding A survey found out that approximately 53 of the grinding circuits around the world use ball mills and 38 use autogenous or semi autogenous grinding and therefore nearly 90 of mining operations are users of balls

Rock Crushers

When a rock has values in it it s then called ore In order to liberate the minerals it needs to be crushed down In days of yore a stamp mill was the primary form of crushing rock but in the modern world there are jaw crushers impact mills and gyrator crushers as well as ball mills They all have their own pros and cons and price tags.

Ball Mill

Ball mills tumble iron or steel balls with the ore The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds The feed to ball mills dry basis is typically 75 vol ore and 25 steel The ball mill is operated in closed circuit with a particle size measurement device and size control cyclones.

What is Gold Ore worth High Grade Mining Ore

Many mines can run profitably on much lower grade ores which might easily reduce the average value of ore down to 25 cents or less per pound Another thing to consider is that the gold within many ores is microscopic particles which require advanced methods to extract such as through cyanide leaching.
