Sulfur Mining and Processing: What to Know General Kinematics
Up until the 20th century sulfur could also be found on salt domes. The once primitive mining methods used during earlier times have developed with the invention of modern-day equipment that makes sulfur mining more efficient and cost-effective. Likewise the mining equipment used today helps reduce waste and chemical exposure.
