The milling process is broadly classified as follows. Peripheral milling. Face milling. End Milling. In peripheral milling, the cutting edges are primarily on the circumference or periphery of the milling cutter and the milled surface is generally parallel to the cutter axis. Peripheral milling Process.

Following mining, transporting, and crushing to the required size, the crushed ore is further processed through a mill and then secondary milling and classification. Water is added into the milling circuit to create a slurry. The slurry is transported to a flotation circuit where the copper mineral is separated from gangue.

To put it simply: lathes are round, milling machines are flat, and boring machines are dry holes. Lathe processing means that the workpiece rotates, but the cutter does not rotate. Milling machine processing is tool rotation, the workpiece does not rotate. Lathe is a machine tool that mainly turns rotating workpieces with turning tools.

The Basics of Copper Mining and Processing. Mined from open pits, copper ore must be crushed as part of the process that occurs between extraction and production. Using today's compact mining equipment, copper ore is extracted from the mine. After the ore is crushed, it's roasted, which helps to convert sulfides to oxides.

Uranium Extraction. Uranium leaching is the process by which the uranium is extracted from the raw ore by reacting the material with acid or base. Fig. 2 shows a general process flow for the uranium extraction process. Prior to the leaching process, the ore is often given preliminary treatments that can include roasting and grinding.

This is the most expensive phase of the mining cycle. The production phase includes extraction, milling and processing of raw materials, such as coal, metals, industrial minerals and aggregate. The length of time a mine is in production depends on the amount and quality of the mineral or metal in the deposit and profitability of the operation.

Ore processing is a 24 hour operation. Ore is stockpiled 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 to raise its pH. Following crushing through a jaw crusher, the ore is fed into the semi autogenous grinding (SAG) mill along with water and steel balls.

Once the ore is on the surface, the process of getting the mineral you want out of the rock can start. Once the mineral is separated from the rest of the rock, the mineral needs to be cleaned so that it can be used. This process can be represented by the following flowchart diagram: In this chapter we will look at each of the steps in more detail.
