A lime slaking and addition system can consists of two systems to control the pH in the rougher and cleaner flotation circuits.A pebble lime silo will dose dry lime to the SAG mill feed belt; a hydrated lime make down system will provide slurry lime to multiple addition points in the flotation circuit. Other lime delivery options are detention slakers and Verti-mill slakers.
The addition of lime slurry to this stream can also remove any oils and/or heavy metals which may cause problems for discharging the stream. This system with lime addition can process the many and varied plant waste streams which are traditionally sent to the bottom ash pond.
Hydrated lime requires care during handling both to prevent it from escaping into the surrounding atmosphere, but also to avert contamination of the hydrated line from any airborne particles. Caution should be exercised to shield the hydrated lime from moisture or from contaminants containing moisture, which may trigger a chemical reaction that ...
When water contains high amounts of magnesium hardness, split treatment may be used. Approximately 80 percent of the water is treated with excess lime to remove magnesium at a pH above 11, after which it is blended with 20 percent of the source water.
An Overview Of Lime Slaking And Factors That Affect The Process By: Mohamad Hassibi Chemco Systems, L.P. November 1999 Revision 1 – February 2009 ABSTRACT Since lime slaking is an integral part of treatment systems in water, wastewater, air pollution, and process industries, its performance will influence the overall effectiveness
Process equipment, instrumentation, and valves selected for use in lime slurry systems should limit cavities, cracks and void areas. Even a small collection point of lime can cause equipment failure and countless hours of downtime and maintenance. The ideal product to supplement lime slurry should be able to clean itself and break apart scale.
Currently, caustic soda and lime users are switching to magnesium hydroxide slurry because of the advantages it offers for biological treatment. Magnesium hydroxide slurry, which is recognized as "the milk of magnesia" for wastewater treatment, has been widely utilized for heavy metal precipitation and acid neutralization of industrial wastewater.
Problems in handling lime will not develop if some simple precautions are taken. Prolonged exposure to hydrated lime may cause drying and chapping of sensitive skin. Where dust may be encountered (in emptying bags or in working in a lime handling plant), workers should wear snugly
