In addition to our standard and high-grade zinc ore, we also offer a low-grade zinc ore that typically contains a zinc concentration of 25-30%. This grade is ideal for applications that require a lower concentration of zinc, such as the production of zinc dust and zinc chemicals.

2011121· The lean zinc oxidized ore was firstly ground to a size below 0.2 mm, followed by alkaline leaching at 90 °C for 120 min in NaOH solution, in which both zinc and lead are effectively extracted. Lead concentrates were then highly selectively and quantitatively produced from the leach solution by adding sodium sulfide as precipitant.

Abstract: The leaching of low grade zinc oxide mining tailings by organic acid as a leaching agent was investigated. Zinc was extracted successfully from sample by citric acid leaching. The effects of solid-to- liquid ratio, acid concentration, reaction time, temperature and ore particle size on the leaching efficiency were studied. The results obtained showed that particle sizes and reaction

Rarely is the ore, as mined, rich enough to be used directly by smelters; it needs to be concentrated. Zinc ores contain 5-15% zinc. To concentrate the ore it is first crushed and then ground to enable optimal separation from the other minerals. Typically, a zinc concentrate contains about 55% of zinc with some copper, lead and iron.
