notwithstanding this, it is expected that there will be casualties among the high cost producers, particularly those that have recently entered the iron ore market with high start up costs and debt levels. the iron ore price is expected to gradually recover from the current lows when production levels better match market demand, but the highs
'staircasing' is one of the safer methods of mining, and it can be used in combination with all other methods. a strategic player can quickly reach all ore layers which will grant them access to the depth at which each type of ore can be found. players can then create miniature mines at each level as a resource for obtaining each respective ore.

(iron bearing) minewater from abandoned mines. the very small iron rich particles (ochre) caused a pronounced turbidity in the main river and, in severe cases, coated the riverbed, smothering invertebrates. this had an effect on fisheries and river ecology in general. iron levels in the catchment in previous years averaged more than two

zinc ore & mines iron ore, ochre & mines coal mining. zinc ore and mines mineralisation. the lead, zinc and copper veins on mendip were deposited by hot mineralising fluids (typically between 50 and 150 ° c) rising up from depth and depositing various minerals as they cooled. the source of the fluids were the deep sedimentary basins either
the deeper you go into the mine, the denser the stone becomes, making it more difficult to mine. as you get deeper more expensive ores will appear. layers determine the types of ore you see, while depth is how far down you are. layers are based on depth. like stone, ores are sold for coins. however, ore typically takes up less storage than stone and is more valuable per unit.
i've noticed i only return from mining expeditions with 25 35 blocks of iron ore, whereas i have no trouble finding tin (usually return with two or so stacks), osmium, or copper. i always mine in the mining dimension, alternating branch mines between y level 40ish and y level 13, with comparable results from each depth.

this causes the host rock to continuously exert pressure on the ore, causing it to collapse at the bottom of the stope, from where it is collected by making newer sub levels. uses. low grade, friable ore deposits; iron, copper, nickel, and gold mines; deposits where both the ore and rock are breakable
