Though gold has been present in Maryland, Pennsylvania, and Vermont, on the range of the Appalachian chain, it has proved inadequate to justify mining explorations, except over a restricted area in Vermont throughout the year 1859. The veins of the southern gold area are found in various rocks of a granitic character, and in the hornblendic rock referred to as diorite, all of which are often in a decomposed condition to the depth of 200 ft. Gold had been gathered to a small extent in numerous locations alongside the ranges of hills on the E. side of the Appalachian chain, between the Potomac and the Coosa river of Alabama; but there was no regular marketplace for its sale, and no account was kept of the portions collected. Mercury is often poured, an hour or two after the commencement of sluicing, into the top of the apparatus, and smaller quantities are also launched at various places along the boxes.

Still it's well-known that there are districts of great richness yet comparatively unworked, and which are likely long to continue so from their extreme unhealthiness and the want of means of comfy subsistence. Here the gold grade is calibrated in terms of grams per ton and there may be very excessive probability that it varies between the location as properly as the depth. The course of the veins is certainly not uniform; they run in numerous directions, and are often tortuous as well as displaced by faults. The most important and most in depth veins exist within the area of the metamorphosed secondary rocks, varying in width from just a few inches to 20 or 30 ft., and usually conforming to the dip and strike of the strata.

Their most common common bearing is N. E. and S. W., with a dip toward the N. W. Veins wherein the quartz gangue is highly crystalline commonly abound in iron pyrites; as they're explored, pyritous copper is mostly met with at some depth. The auriferous amalgam is removed from copper plates by first warming after which scraping them.
More commonly gold occurs associated with other minerals, chiefly (in decomposed ores) the oxides of iron, and (in stable ores) iron and copper pyrites, galena, blende, mispickel (all of which could also be auriferous), bismuth, stibnite, magnetite, hematite, numerous spars, and quartz. Sluice washing is generally carried on during the day only; however when water is abundant and cheap, the work could also be continued all through the entire twenty-4 hours. This apparatus is both gradual and wasteful in operation; however it's low-cost and portable, and requires little water, since the same water may be utilized in it over and سعر الذهب اليوم باليورو over again. Water flows into the mortar with the ore; and the finely divided product is splashed by the stamps via screens of wire cloth or perforated sheet iron, set in the partitions of the mortar. The stem matches under into the stamp head, a cylinder of tough solid iron, furnished on its decrease face with a hard iron shoe, which can be changed when worn out. The stem was formerly made from ash or different exhausting straight-grained wooden, about 6 in.
