What is Sulfide Mining? | Mining Action Group

Metallic sulfide mining (aka hard rock mining) is the practice of extracting metals such as nickel, gold and copper from a sulfide-rich ore body. Sulfides are a geologic byproduct of mining in this area, and by exposing sulfides to the air and water in our atmosphere, sulfuric acid can be created — threatening to poison the nearby water ...

Sulfation: What is it and How to Avoid it?

Sulfation is a buildup of lead sulfate crystals and is the number one cause of early battery failure in lead-acid batteries.. How does battery sulfation occur. Sulfation occurs when a battery is deprived of a full charge, it builds up and remains on battery plates. When too much sulfation occurs, it can impede the chemical to electrical conversion and greatly impact battery performance.
