Pennsylvania Iron Furnaces - OLD INDUSTRY
Around the area west of Philadelphia, the Appalachian Mountains possessed beds of iron ore, hardwoods, and plenty of limestone deposits. As the colonialists spread across the state, they built iron furnaces in the Susquehanna Region, and then farther to the west, adjoining the Hanging Rock Iron Region of Southern Ohio and Northern Kentucky.

Gold Processing Methods & Gold Ore Extraction
Of all the methods of extracting gold & processing it from its ore, I used a few to evaluate two principal flowsheets in this case study. The flowsheets utilized operations that involved flotation, cyanidation and gravity concentration. Tests that mirror each of these unit operations were utilized to evaluate the principal flowsheets.

Eight Natural Geologic Signs Pointing Toward Gold
The problem is that gold occurs in many types of deposits, and what indicators work great for one type of deposit don't always work well for another. As an example, in some places the presence of vein quartz on the ground is a valuable indicator, yet I have been in places where there is so much vein quartz everywhere that is worthless as an

A Method for Leaching or Dissolving Gold from Ores or
native gold from gold-bearing ores. It has been known for more than a century that alkaline solutions of alkali-metal cyanides (e.g., NaCN, KCN) dissolve gold under aerated conditions. The dis-solution of metallic gold is due to the strong complexing capabilities of cya-nide anions combined with the oxidizing properties of the dissolved molecular

Gold Ore Sorting : TOMRA
Gold ores are typically amenable to sensor-based ore sorting to some degree, and this is usually accomplished with XRT or laser sensors, or a combination of both. A two-step sorting flow-sheet consisting of an XRT rougher plus a laser scavenger (or alternatively, a laser rougher and an XRT scavenger) has already proved an optimal recovery
