Generally, mineral processing begins when an ore is delivered from a mine, to a processing facility. At this point, the ore is called run-of-mine material because there has been no treatment performed on it. There are three primary types of run-of-mine materials: 1. Run-of-mine consisting of useful materials.

Fine grinding, to P80 sizes as low as 7 μm, is becoming increasingly important as mines treat ores with smaller liberation sizes. This grinding is typically done using stirred mills such as the Isamill or Stirred Media Detritor. While fine grinding consumes less energy than primary grinding, it can still account for a substantial part of a mill's energy budget. Overall …

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
Details 
The types of mill normally encountered can further be classified according to the method of feeding the raw material to, and the removal of the final product from the mill. These classes are: Batch mills. Grate discharge mills. Trunnion overflow mills. Air-swept mills. The principles of these mills are illustrated in Fig. 1.4 and Fig. 1.5.

Gold ore is considered free-milling when over 90% of the gold can be recovered by a conventional gravity-cyanidation process with low reagent consumptions at a grind size of 80% passing 75 µm. Some examples of free-milling gold ores include quartz-veined deposits and oxidized ores. Sulfide-Associated Gold

Gold flotation. Flotation process is widely used for lode gold processing. In most cases, the flotation method has a good effect in sulfide-containing gold ore with high floatability. In addition, the flotation process is also used for polymetallic gold-bearing ores such as gold-copper, gold-lead, gold-copper-lead-zinc-sulfur ore.

Typically, mill tailings range from sand to silt-clay in particle size (40 to 90 percent passing a 0.075 mm (No. 200) sieve), depending on the degree of processing needed to recover the ore. The basic mineral processing techniques involved in the milling or concentrating of ore are crushing, then separation of the ore from the impurities.

Ore is mined and processed at an onsite flotation processing plant capable of treating up to 24 million tonnes per annum (Mtpa). The plant currently recovers copper, gold and silver into a saleable concentrate. The primary ore is crushed and ground using Semi-Autogenous Grinding and Ball mills to a final grain size of approximately 180 microns.

An ore is a type of rock that contains minerals with important elements such as metals. Ores are extracted through mining; they are then refined to extract the valuable element(s). The grade or concentration of an ore mineral, or metal, as well as its form of occurrence, will directly affect the costs associated with mining it.

Ore is stockpiled (1) at the processing plant, and the process begins by feeding the ore into a hopper with a loader. The ore is conveyed, and lime is added (2) to raise the pH of the ore. Following crushing through a jaw crusher (3), the ore is fed into the semi autogenous grinding (SAG) mill (4) along with water and steel balls.

Extracted ore, no matter the mineral, is typically first crushed, and then must go through a beneficiation process to remove the unwanted impurities. Beneficiation can vary significantly from one ore type to the next. In most cases, however, beneficiation is carried out through a wet process that necessitates a subsequent drying step.
