Introduction

Coal and coal gangue leaching with water, in which harmful elements such as mercury, arsenic, fluorine, copper, nickel, zinc, lead, cadmium and chromium migration and transformation, polluting the environment. This standard In order to simulate the water leaching conditions of coal and coal gangue under natural conditions, water and coal gangue leaching tests were carried out to determine the pH of the leachate Value and the concentration of mercury, arsenic, fluorine, copper, nickel, zinc, lead, cadmium and chromium therein. According to the provisions of this standard leaching solution and leaching solution test results, reference Appendix A to determine the leaching toxicity of coal and coal gangue in order to make a scientific assessment of the environmental impact of coal and coal gangue and take reasonable treatment Measures. Coal and coal gangue leaching test methods
