Mining

The acidic wastewater resulting from mining operations requires treatment in order to prevent adverse impacts to rivers and streams wastewater.

Mining Applications

Acid mine drainage is a major pollutant of surface water in some regions, primarily from water flowing through abandoned mines that contain sulfur-bearing minerals. Characterized by low pH and toxic metal content, it can be mitigated through the use of activated carbon and ion exchange.

Heavy metals are found in many industrial wastewater as well as sometimes occurring naturally in some groundwaters. Typically present in relatively low levels as compared to other dissolved ions, the ability to selectively remove these ions is accomplished with a specialty weak acid cation resin.

Ammonium ion forms when pH is less than 9 (preferably less than 8). Ammonium is a monovalent cation. Cation resins such as CG8 and CG10 have modest selectivity for ammonium ion compared to sodium but poor selectivity compared to hardness ions such as calcium and magnesium. SIR-600 has very high selectivity for ammonium but fairly low capacity and requires a rather large salt dose (typically at least 30 lbs NaCl per cu ft).

Mercury is a chemical element with symbol Hg and atomic number 80. It is commonly known as quicksilver and was formerly named hydrargyrum. A heavy, silvery d-block element, mercury is the only metallic element that is liquid at standard conditions for temperature and pressure; the only other element that is liquid under these conditions is bromine, though metals such as caesium, gallium, and rubidium melt just above room temperature.
Mercury occurs in deposits throughout the world mostly as cinnabar (mercuric sulfide). The red pigment vermilion is obtained by grinding natural cinnabar or synthetic mercuric sulfide.
Mercury is used in thermometers, barometers, manometers, sphygmomanometers, float valves, mercury switches, mercury relays, fluorescent lamps and other devices, though concerns about the element’s toxicity have led to mercury thermometers and sphygmomanometers being largely phased out in clinical environments in favor of alternatives such as alcohol- or galinstan-filled glass thermometers and thermistor- or infrared-based electronic instruments.
Mercury forms amalgams with many metals and was once used in dental fillings and to extract gold from various ores. Mercury is still used as a preservative in vaccines despite its know toxicity. Commercial uses of mercury have been curtailed, however mercury emissions from coal fired power plants remain a dominant source of mercury in our environment.

Mercury is a potent neurotoxin. Most mercury in our environment currently comes from coal fired power plants. Aerosol mercury emissions remain in the upper atmosphere for long periods of time, making this a global problem. The selective resins with thiol functionality have high affinity for cationic mercury.

Organo mercury compounds, notably methyl mercury form from the reaction of elemental or cationic mercury with organic matter.

Strong base anion resin have good affinity for nitrate. The higher amines (triethylamine, tributylamine, etc.) have increased affinity for nitrate and decreased affinity for divalent ions such as sulfate, making them preferred for many applications.
