5Newcrest Mining Ltd Cadia Hill Gold Mine, Australia The design of the comminution circuit and selection of mill Laboratory test work data, shown in Table 1, indicated hard and Rock Type crusher. Unfortunately, the jaw crusher was difficult to set to a fine crush size of
In mineral processing or metallurgy, the first stage of comminution is crushing. Depending of the type of rock (geometallurgy) to be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing is used on hard and abrasive rocks by placing them between a high wearresistant plate/surface. Less abrasive and softer rocks or stones

#0183;#32;Abstract The paper reports the progress of a research project using rock samples from a large coppergold mining project. The orebody contains a mixture of hard rock, softer material, and clays (sericite), in proportions that are expected to vary throughout the minelife. The feasibility of a novel comminution circuit, using an autogenous (AG) mill/scrubber and parallel trains of cone
Comminution Circuits for Gold Ore Processing ScienceDirect South Africa, long known for tube mills (lowaspect semiautogenous mills), continues to contribute. Highpressure grinding roll (HPGR) installations are now well established in the hardrock mining industry, including gold applications, and are now routinely considered as a comminution circuit option. get price

asked three experts at to the right comminution circuit design. In hard rock applications the designer may favor growth and demand in metals like copper and gold.
Of the numerous major gold mining operations around the world, most utilize a primary crushing circuit which flows into a SAG mill circuit and then a ball mill circuit. The primary reason for the significant comminution circuits is because in gold mining the grades are notably low and thus excessive waste material is present, resulting in high mill feed rates.
