Jun 05, 2021 · Abstract. In this research, the effect of different citric acid concentrations, ammonia concentration, temperature, leaching time, stirring speed and liquidtosolid ratio on the zinc leaching from lowgrade zinc oxide ore in a NH 3H 3 C 6 H 5 O 7H 2 O system were studied. The results showed that the zinc leaching rate is only % when the citric acid concentration is 0 M, and the leaching ...

Essentially complete recovery of copper from an oxide ore was obtained in a leaching operation by the Bureau of Mines using ethylenediaminetetraacetic acid (EDTA) as a chelative leachant. The EDTA was most effective in the form of a trisodium salt. Copper can be recovered as metal from leach solutions by reducing agents such as hydrogen, HCHO, and CO.

Potassium silie alteration is formed as a replacement of plagioclase and mafic silie minerals, at temperatures in the region of 600–450 C. Potassic (or Ksilie) alteration is characterized by the formation of new Kfeldspar and/or biotite (green colored and Ferich), usually together with minor sericite, chlorite, and quartz.

A process is provided for heap leaching ore to recover nickel. The process is particularly effective for ores that have a tangible clay component (, greater than about 10% by weight). The process includes sizing the ore (where necessary), forming pellets by contacting ore with a lixiviant and agglomerating. The pellets are formed into a heap and leached with sulfuric acid to extract the ...

In heap leaching, agglomeration of clay rich ores is commonly used and may prevent plugging phenomena within heaps, but is not always successful. In order to better understand the heap leaching process of uranium ore agglomerates, a multiscale approach, based on 10cm and meterscale columns, was used to achieve a Representative Elementary ...
