Grade Control
Grade Control is a crucial process in mining and quarrying that helps companies monitor and manage the quality of materials being extracted. It's like quality control for rocks and minerals. Workers use this process to make sure they're getting the right type and quality of materials from the quarry or mine, which helps the company maintain product standards and maximize profit. They might check things like mineral content, rock size, or material purity. Think of it as sorting ingredients in a kitchen - you want to make sure you're using the right things in the right amounts.
