Graystone Company Announces Copper Campaign #2 Update.
About this update from The Graystone Company, Inc.
[{"type":"text","content":"\n \n The Graystone \n Company (OTC: GYST) announced today that its wholly owned \n subsidiary, Grupo Mineral Inca, SAC (GMI) has compiled approximately 130 \n tons of high grade copper ore so far for its Copper Campaign #2. The \n company has started shipping the ore to its processing plant in Nazca, \n Peru. The company conducted an aggregate test sampling of the 130 tons \n of ore and the percentage of copper in the ore is currently testing at \n an estimated 20-22% increase compared to the final results from \n profitable campaign #1.\n \n \n In addition, the lab results also indicate a recoverable amount of gold, \n which the company’s metal ore engineer will also recover with the copper \n as a concentrate via froth flotation.\n \n \n The process of froth flotation entails crushing and grinding the ore to \n a fine size. This fine grinding separates the individual mineral \n particles from the waste rock and other junk mineral particles. The \n grinding is done in water with the resultant slurry called the pulp. The \n pulp is processed in the flotation cells, which agitate the mixture and \n introduce air as small bubbles. The ability of a mineral to float \n depends upon its surface properties. Chemical modification of these \n properties enables the mineral particles to attach to an air bubble in \n the flotation cell. The air bubble and mineral particle rise through the \n pulp to the surface of the froth or foam that is present on the \n flotation cell. Even though the air bubbles often break at this point, \n the mineral remains on the surface of the froth. The mineral is \n physically separated from the remaining pulp material and is removed for \n further processing.\n \n \n Pictures and videos of GMI conducting this process during campaign #1 \n are located on the company’s YouTube and Flickr media streams via links \n at www.graystone1.com\n \n \n As in campaign #1, the company intends on selling it’s processed \n concentrate to its Chinese concentrate buyers.\n \n \n Because of the higher quality ore and our repeat business, the \n processing plant has reduced GMI’s minimum quota from 200 tons of ore to \n 150 tons.\n \n \n GMI is also in the final stages of negotiating a 45 ton bulk ore \n purchase that, if completed this week, would enable the company to start \n processing its ore as e...
