The Lusatian mining district is one of the three large lignite mining districts in Germany. After reunification a large part of the mines was closed due to economic and ecological reasons. The remaining mines are still in operation. After closing the mines in the nineties the pitlakes were flooded
Coagulants commonly used over the past one hundred years include calcium carbonate (lime), aluminum sulfate (alum) and calcium sulfate (gypsum). Natural materials such as starch and starch derivatives, cellulose compounds, polysaccharide gums, and proteinaceous materials were formerly used as flocculants (Kleber 1973).
Industrial Wastewater Treatment Market by Type (Coagulants, Flocculants, Biocides Disinfectants), EndUse Industry (Power Generation, Mining, Chemical) and Region (APAC, Europe, North America, MEA, South Market research report and industry analysis
May 07, 2018· The mining industry has been leaching copper since the late 1960's from oxide ores, low grade secondary sulfide ores, and primary sulfide concentrates with aqueous acid or ammonia solutions, followed by solvent extraction (SX.
Flocculants, with their very high molecular weights (long monomer chain ) and their charge content, fix the destabilized particles and aggregates along the polymer chain. There follows, during the flocculation step,an increase in the size of the particlespresent in the water phase resulting in the formation of flocs.
Ludwigshafen, Germany – April 19, 2017 – Driven by continued increases in cost of raw materials, transportation, and energy, BASF will increase prices by 3 to 6% for flocculants for the mining industry with immediate effect as contracts allow, depending on products and delivery locations.
Mining Industry Treatment Process Wastewater from extractive operations ( bauxite, coal, copper, gold, silver, diamonds, iron, precious metals, lead, limestone, magnesite, nickel, phosphate, oil shale, rock salt, tin, uranium, molybdenum) has to be properly managed in order to prevent any water or soil pollution arising from acid or alkaline leaching of heavy metals.

Executive summary vi Management of tailings and wasterock in mining. Typical techniques applied in mineral processing are: comminution screening and hydrocycloning gravity concentration flotation sorting magnetic separation electrostatic separation leaching thickening filtration.
Thickening, Filtering, Metals Treatment, Dewatering, Deers. The extraction of minerals demands the use of large volumes of water resulting in a requirement to use ...
Some frac sand mines (mines that extract silica sand to be used for hydraulic fracturing) use products called flocculants to remove silt and clay in the sand washing process. These products are generally considered to be environmentally safe; however, they often contain low concentrations of chemicals (acrylamide and DADMAC) that are of potential concern.
Flocculants Flocculation is the step where destabilized colloidal particles (or the particles formed during the coagulation step) are assembled into aggregates and can then be .

Natural flocculants have been utilised for many years, and even though most of their original applications are now performed using synthetic polymers, there are some specialist areas within mining and food processing where they are still employed. Natural flocculants are derived from plant and animal products with the principal types being ...
The agreement provides the opportunity to participate as a supplier of mining industry inputs with a tax rate of 0% between the parties for chemical products for the flotation of minerals, and other processes performed in the mining industry including leachates, depressants, ing agents, flocculants, sodium cyanide, sodium pentasulfide, among others.
Some people have raised concerns about the high demand for water, not only for use in frac sand mining but also for industrial agriculture in the region. Another concern is the use of chemicals known as flocculants, which are used in the wash plants [the raw materials must be washed] and processing plants.
Custom manufacturer of flocculants including emulsions and solutions. Analytical and laboratory services are also available. Power electrical utilities, food processing, hospital and municipal facilities, commercial properties, soil remediation, mining, textile and chemical manufacturing, pulp, paper and oil refining industries served.
Veolia supplied a total mine water treatment solution to this operation. The solution includes the supply of cooling water treatment products, mine water treatment and clarification products (pH control and flocculants). Permanent onsite technical teams monitor and administer products into the mine water treatment systems.
