In this study, extraction temperature was maintained in the range of 70-80°C, only KOH concentration and extraction time was manipulated. Thus the experiment was designed to use the range of process parameters as shown in Table 1 .

1 Extraction of Natural Products from Plants – An Introduction Hans - J ö rg Bart 1.1 Introduction The history of the extraction of natural products dates back to Mesopotamian and Egyptian times, where production of perfumes or pharmaceutically - active oils and waxes was a major business.
Nepheline syenite is a complex rock consisting of different mineral phases such as nepheline, alkali feldspar, and biotite. It is a promising source for the recovery of potassium and alumina values.
Worldwide, most potash is mined conventionally. But by using liquid extraction, St. Germaine says the Michigan product is 99% pure. Impoted potash "gets loaded on a train, loaded on boat, loaded on a truck, and it has a lot more fines that plug up applicators," he says.
Potash Ridge will rely on direct extraction methods to become the lowest cost producer of premium SOP in North America. Using this approach, Potash Ridge expects to produce from its Blawn Mountain prospect for about $250 per tonne all in.
Potassium (K) is a chemical element with the atomic number 19. Pure potassium is a white metal that is very soft and burns in water. It has few uses in elemental form since it's so reactive with water, but potassium compounds have a wide range of applications, especially as fertilizer.

Sirius Exploration is a company that's changed dramatically over the past year or so. In the report and accounts to March 2009, management refers to a "year of transformation", and in that time the company has moved from being a gold, iron, copper based minerals explorer to a focus on potash and salt. Er, potash?
However, potash feldspar is found in many parts of the world. Therefore, it is very significant to study extracting potassium from potash feldspar. The studied extracting process was following, the calcium chloride was used as leaching agent, and melted under high temperature, then made potash feldspar be leached so as to extract potassium.
Potash (with the means to extract it from 1000m below ground) may not be a limiting factor, but other resources (and phosphorus most certainly is a key one). So the good news on potash is only mild relief.

Extraction wells are installed at the low points to pump the potash rich brine to the surface, where it is placed into 400 acres of shallow evaporation ponds just southwest of the mine. Blue dye, similar to food coloring, is added to the evaporation pond brines, to aid in absorption of sunlight.

Electrolytic methods for extracting potash from feldspar seem to be prohibitive in cost, because of the high power consumption per unit of potash extracted. At best, under the conditions employed, electrolysis gives a very dilute solution which must be purified and evaporated.
Potash: The word potash is said to be conventionally derived from pot-ash-the ash residue after combustion of organic material (plant materials) (Wikipedia, 2007) and sometimes, it is so-called because K is the main alkali metal in the ash. However, current researches have shown that only a fraction of ash is potash.
Room and pillar deformation were measured in conjunction with a relatively new type of mining operation in a southeastern New Mexico potash mine. The extraction ration was approximately 90 percent in a first mining operation. Due to severe deformations encountered, instrumentation had to be ...
EVART — After hearing concerns from community members Tuesday, the Evart Township board unanimously approved the establishment of an industrial district for the extraction of potash.

Studies on extraction of potassium values from nepheline syenite Its demand for agricultural use is growing steadily at 3–3.5% per annum ( Manning, 2010 ). Since India does not have any commercial resources of potash, a large quantity is imported every year from the global market to meet the agricultural demand.
