Copper Heap Leaching & SX-EW Slideshow MineralsEd

Heap leaching & SX-EW is a method of extracting pure copper from oxide ore by placing the crushed ore on a pad in a heap and spraying the leaching solution, sulphuric acid, over the heap. The acid trickles through the heap and dissolves the copper mineral into solution. The leach solution collects at the bottom of the pad in a collection pond.

Improvements in Copper heap leaching by use of wetting agents

Heap leaching belongs to the group of percolation leaching processes and operates over ground. The procedure is illustrated in Figure 1.The oxide copper ore is piled up on leach pads, which have a slight slope of approx. 3° and a rubber lining, which seals the ground under the heap.

Hawaii beach sand composition To-Hawaii

Black sand beaches are created when lava flows into the ocean. Black sand beaches usually have a short life span (up to a few hundred years) because as soon as the volcanic activity stops, so does the source of the black sand. Over the years the ocean erodes the beach and the waves carry the black sand
