Liquid/solid separation equipment for tailings
The advantages of paste thickeners in tailings circuits have been well-established for most minerals. The type of paste thickener underflow generally used for surface stacking of tailings is called “thickened tailings.” Thickened tailings are a suspension of solids which are relatively non-settling and non-segregating and which have a higher concentration and viscosity than that of conventional tailings. Common applications include a thickener with underflow pumps that are typically centrifugal and ...

Liquid/solid separation equipment for steel and manufacturing
Coke Wastewater Treatment: Heating coal over 1100 Co in the absence of oxygen produces metallurgical coke. This process provides both heat and carbon (coke) required for iron production. During this process the volatile materials contained in the coal are driven off, leaving coke as the product. Gas produced by coking is withdrawn by means of blowers to recover energy-rich byproducts, including methane. Ammonia stills are the principal means of recovery. Recycled scrubber water is used as a coolant. Scrubber waste ...

Industrial solutions for cooling tower, boiler feed pretreatment
Cold Lime Softening: Hard water is water that has high mineral content. The name comes from the hard scale that forms when this water is boiled. It is not harmful to human health, but in the industrial setting it causes costly breakdowns in boilers, cooling towers, and other water handling equipment. The divalent cations Mg and Ca are the most frequently found minerals causing hard water. These ions enter water supplies by leaching from minerals in underground aquifers. ...

Liquid/solid separation equipment for refinery, chemical and petrochemical
Cracking in a refinery is a process where the long organic chains in oil are broken to produce shorter chain organics that are more valuable than the oil. Fluid catalytic cracking (FCC) has generally replaced thermal cracking of petroleum hydrocarbon feed stocks. FCC produces more gasoline with a higher octane rating. FCC’s byproduct gases are more olefinic and valuable than those produced by thermal ...

Liquid/solid separation equipment for coal mining and preparation
Coal Preparation Circuit: Three quarters of American coal is mined east of the Mississippi River. Half of this is “prepared” coal. Coal preparation offers a number of commercial and environmental benefits. These include increased quality and commercial value of saleable coal by achieving 75-80% ash reduction and 15-80% trace element reduction. Cleaned coal reduces transportation costs as well as reduced quantities of combustion ash requiring disposal. Coal preparation can also make marginal coal ...

Liquid/solid separation equipment for paste thickening and backfill
Mine backfill is defined as the material used to fill the cavities (i.e., stopes) created by underground mining. Backfilling can be a means to dispose of sludge and/or tailings which may contain hazardous materials and to reduce surface environmental impacts by storing tailings underground. Alternately, backfilling with nonhazardous materials can allow for mining productivity improvements. To these materials are added a variety of fillers such as fly ash, course sand, or gravels along with a binder, such as ...

Solids separation filter technology solutions for pulp & paper industry
Water is used in nearly every step of the manufacturing process for a pulp and paper mill. So, of course these facilities have large volumes of wastewater to treat and sludge to dispose of. To save costs, many facilities would like to recover excess pulp fiber from their wastewater to be reused in the production line. For those facilities not recovering fibers, our integrated thickening and dewatering processes are effective with fibrous material and can reduce the volume of sludge and associated disposal ...
