Iron ore extraction techniques
Iron ore was won by drilling and blasting (Figure 7.1).As mining technology generally developed, so did drilling techniques and the explosives used. Smith (1990) reported that the Cleveland deposit was associated with a very strong stone roof rock (known as "dogger") allowing mine drivages to be self-supporting. However, he states …

Use Better Digging Techniques to Get More Out of Your Excavator
Lower the digging speed and use a bucket with wide teeth to prevent excessive soil disturbance and cave-ins. Gradually scoop out material in small increments, ensuring stability while maximizing productivity. Additionally, consider using tracks with wider shoes to reduce ground pressure, minimizing the risk of sinking in loose terrains.

It is a process of ore preparation, milling, and ore dressing or ore beneficiation. Ore dressing is a process of mechanically separating the grains of ore minerals from the gangue minerals.(PDF) Overview of Mineral Processing Methods
…What are the different types of ore-dressing methods?Ore-dressing methods fall naturally into two general subdivisions— (1) concentration methods and (2) direct-recovery methods (amalgamation and leaching or wet methods). Concentration methods are employed to remove worthless gangue material and concentrate the valuable minerals of the crude ore in a smaller bulk.Ore Dressing Methods
Is ore dressing a milling process?Although perhaps not ore dressing in the strict sense of the term, the direct extraction of the metals (especially the precious metals) from the ores also is considered here as an ore-dressing or a "milling" process.Ore Dressing Methods
