Filter pressing is a viable and proven tailings management alternative. Building on the experience at successful dry stack operations, operating at production rates of up to 30,000 tonnes per day, filter pressed dry stacking can be and is being considered as an economically feasible tailings management alternative for even higher production rates.
Tailings filtration and dry stacking reduces the risk of liquefaction, improves rehabilitation and minimises waterpared to conventional wet impoundments and is therefore considered to be environmental best practice for tailings management.

Dry Stacking of Tailings Filtered Tailings Figure 1: The La Coipa dry stack facility in Chile Courtesy Anglo American/Debswana Introduction. Dewatering tailings to higher degrees than paste produces a filtered wet saturated and dry unsaturated cake that can no longer be transported by pipeline due to its low moisture content. These filtered tailings are normally transported by conveyor
Due to the considerable expense of using filtration to achieve dry stack tailings, air drying of paste or thickened tails is an option worth evaluating. In certain situations, pastebined with an inexpensive, widely applicable air drying scheme can permit bulk handling of the tailings.
Dry stacked tailings now large scale It is widely agreed that DST is the most sustainable route for eliminating the environmental risk of tailings dam failures, while at the same time enabling the mining industry to continue even in water scarce areas by enabling a recirculation of the process water with a minimum of water intake.
Dry stacking of tailings at La Coipa has been possible due to advancements in large capacity horizontal belt vacuum filters. The tailings 18,000t/d are dewatered to contain <20 water content depending on the specific gravity allowing them to be either trucked or transported by conveyor to the disposal site.

The risk of tailings dam failure couldpletely avoided by dewatering and dry stacking the tailings. Xinhai, with its strong legacy in dewatering solutions, takes the filtration technology to the next level withmitment to maximize water recovery and reuse.
Discard the liquid that will have emerged from the vegetables, then rinse and dry the vegetables before pickling or canning as usual. The salt helps to pull the moisture out of the vegetables and makes them crisper in the end. Measure or weigh carefully, because the proportion of fresh food to brine and other ingredients will affect flavor and, many times, safety. Using the Right Salt. Salt

I've found pickling confusing possibly because I'm thick. I found that this works, though: myDictionaryString=strmyDictionary Which you can then write to a text file. I gave up trying to use pickle as I was getting errors telling me to write integers to a .dat file. I apologise for not using pickle.

The liquid hydrochloric acid used in pickling is actually a solution of hydrogen chloride gas in water. Raw acid is generally purchased as â˜20°Bauméâ, which means it has a specific gravity of 1.16 and contains about 32 hydrogen chloride HCl and 68 water. For pickling purposes, this acid is usually diluted to about 18 22 HCl. The HCl solution used in pickling emits HCl
