6 Stages of the Mining Process BOSS MagazineThe mining process is responsible for much of the energy we use and products we consume. Mining has been a vital part of American economyand the stages of the mining process have had little fluctuation. However, the process of mining for ore is intricate and requires meticulous work procedures to be efficient and effective. This is why we have broken down the mining process into six comprehensive steps.

The first stage in the mining process calls for skilled workers or AIto apply their geological knowledge in identifying areas where a particular ore can be found. There are two methods workers and machines can employ during this stage:

In the second stage of mining, core samples are collected for the purpose of evaluating the grade and weight of deposits. Diamond drillsare used to obtain samples. Once the reserve estimationmeaning, the value of the depositis determined, a feasibility study must then be conducted to help determine whether to abandon or develop the deposit.

This stage of the mining process requires establishing a path to the mineral deposit. That path, however, requires more than excavation. In order to even begin work, mining rights must be acquired, access roads must be constructed to help workers navigate the site, and a power source must be established.

Once the ore has been processed and shipped away for sale, the final step of the mining process begins. The land which was used to obtain these resources must be rehabilitated as much as possible. The objectives of this process include: 1. minimizing environmental effects 2. ensuring public health and safety 3. preserving water quality 4. establishing new landforms and vegetation 5. removing waste and hazardous material 6. stabilizing land to protect against erosion

What is Gold Ore worth? High Grade Mining OreFirst, lets look at the textbook definition of ore. Ore is defined as a naturally occurring mineral containing a valuable constituent (as metal) for which it is mined and worked. In other word, ore is the most basic raw form of a mineral, which requires additional processing for the valuable minerals (gold) to be removed.
