The composition of wastewater from uranium ore acid heap leaching is shown in Table 1. It can be seen from Table 1 that if lime is neutralized to pH 7-8, most of the contaminated components in the wastewater (except radium) can be removed by precipitation. The most widely used treatment for uranium

1,          Before lifting, check the brakes of the crane and the integrity of the steel rope. Whether the objects to be hoisted are bundled to prevent falling off or damage the equipment. 2,          When lifting, it should be hoisted vertically.

Acid heap leaching uranium produced by waste water, waste, emissions heap leaching is much more complicated than gold ore cyanide pollution of the environment, much more serious. On the one hand, the uranium mine itself is radioactive, on the other hand, the acid has a greater impact on the environ

First, the source, characteristics and harm of mine wastewater (1) Source of mine wastewater Mine wastewater mainly comes from mine production. According to the production process, it can be divided into mining operation wastewater and mineral processing wastewater; according to the pH value of w

At present, black metal mining waste water treatment processing plant to use more common thickener for natural sedimentation, water purification poor results. For example, a mine will pump 485m 3 /h of wastewater into a natural concentrator with a diameter of 18m for natural precipitation. When the
