the techniques used for the extraction of tin from dartmoor followed a progression from streaming through open cast mining to underground mining. today, there are extensive archaeological remains of these three phases of the industry, as well as of the several stages of processing that were necessary to convert the ore to tin metal.
one of four processing plants in the wolfram area, the treatment plant provides physical evidence of an important shift in milling practices and employment in the hodgkinson river area, from gold to other mineral mining and processing. the treatment plant represents an uncommon milling practice in north queensland, that of the mineral, wolfram .
the rejected minerals and rocks liberated through mining and processing have the potential to damage the environment by releasing toxic metals arsenic and mercury being two major culprits , by acid drainage usually by microbial action on sulfide ores , or by damaging aquatic wildlife that rely on clear water vs suspensions .
'mining in x' has seems to have the superior claim. 'mining in x' is the universal category usage and analogous to the likewise universal 'agriculture in x'. topics under 'mining' do include primary mineral processing e.g. smelting, refining , though if this broader meaning is insufficiently clear, 'mining industry of x' may add some clarity .

a thickening agent or thickener is a substance which can increase the viscosity of a liquid without substantially changing its other properties. edible thickeners are commonly used to thicken sauces, soups, and puddings without altering their taste; thickeners are also used in paints, inks, explosives, and cosmetics.. thickeners may also improve the suspension of other ingredients or emulsions .
