What is the benefit of ores obtained from silk touch?
Meaning, as i said, the purpose of silk touch is to collect the raw item, either for decoration, to remove smelting or to save time and mining uses for some items. It also allows you to transplant Grass/Mycelium to areas that don't normally have it without building extensive dirt bridges.

The Environmental Problems Caused by Mining | Earth.Org
The infrastructure created by mining operations in remote, untouched landscapes can lead to improved access to these regions which may result in further human-caused disturbance to the local ecological systems. The impact of mining operations on the surrounding land is also closely linked to the ecological setting of the mining sites.

Open Pit Mining
Open-pit mining, also known as opencast mining, open-cut mining, and strip mining, means a process of digging out rock or minerals from the earth by their elimination from an open pit or borrow. The word is used to distinguish this type of mining from extractive methods that need tunneling into the earth. Open-pit mines are used when deposits ...

How do we extract minerals? | U.S. Geological Survey
The primary methods used to extract minerals from the ground are: Underground mining. Surface (open pit) mining. Placer mining. The location and shape of the deposit, strength of the rock, ore grade, mining costs, and current market price of the commodity are some of the determining factors for selecting which mining method to use.

Types of Mining Methods | Cummins Inc.
Open-pit mining. Open-pit mining is the activity of removing the earth to access the mineral deposits and continuing to do it vertically in an open-pit. This method is best suited for mineral deposits that are close to the surface of the earth but are not accumulated in a horizontal manner. Open-pit mining often impacts a narrower surface area.

Iron Ore Mining – The process of iron ore mining %y
Iron ore mining is the process of extracting iron from its natural form, which is found in rocks and minerals. The process begins by removing the topsoil from the area to be mined. This soil is then replaced and compacted to make sure that there is no waterlogging or runoff. The next step is to drill holes into the rock, so that explosives can ...

Iron ore | BHP
Iron ores are rocks and minerals from which metallic iron can be extracted. There are four main types of iron ore deposit: massive hematite, which is the most commonly mined, magnetite, titanomagnetite, and pisolitic ironstone. These ores vary in colour from dark grey, through to deep purple, rusty red and bright yellow.
