Sulfur. Sulfur can occur in ground water in two forms: sulfides and sulfates. Sulfides are naturally occurring in much of the United States in limestone containing organic materials; ground water affected by oil, gas, and coal deposits; in marshes and manure pits; and in the byproduct of well-established iron bio films.

INDUSTRIAL MINERALS: SULPHUR POWDER

Nov 02, 2017Elemental sulfur was once extracted from salt domes where it sometimes occurs in nearly pure form, but this method has been obsolete since the late 20th century. Today, almost all elemental sulfur is produced as a byproduct of removing sulfur-containing contaminants from natural gas and petroleum.The element's largest commercial use (after mostly being converted to sulfuric acid) is to produce

A New Process For Sulfate Removal From Industrial Waters

As with the initial sulfate precipitation step, a mixing time of 40 to 60 minutes is adequate. This sludge is dewatered separately in a filter press to prevent contamination of the pure gypsum or ettringite. In a typical metal-bearing wastewater, approximately 45 pounds of gypsum and metals sludge are produced per 1000 gallons of water treated.

Silicosis

Silicosis. Silicosis is a long-term lung disease caused by inhaling large amounts of crystalline silica dust, usually over many years. Silica is a substance naturally found in certain types of stone, rock, sand and clay. Working with these materials can create a very fine dust that can be easily inhaled.
