  • Water pumping windmillsBackwoods Home Magazine

    Standing tall like a giant sunflower in a sea of undulating prairie grasses or in any rural setting a windmill is a thing of beauty. Not only are water pumping windmills a joy to watch but they are incredibly useful. Powered only by wind they work like quietly-purring nonpolluting creatures to keep our storage tanks overflowing with fresh water.

    "Flotation reagent selection is paramount and test work is necessary to ensure the optimum reagent suite is utilised. If the ore contains a low amount of iron sulphides xanthate collectors are often suitable to float copper sulphideminerals. If native gold is present dithiophosphates can be used which are less selective to iron sulphides.
