In this study, two types of waste from the mining district of La Union (Spain) were used to study their use as a component of road wearing courses. The physical and mechanical characteristics were determined to identify the optimal content of bitumen, as well as the fatigue resistance using the four-point beam fatigue test, in all the mixtures manufactured. The mine tailings exhibited adequate

Dangers of Lead

Tailings water, especially heavy metal ions-contained tailings water, must be treated to the standards before discharge. Lead-zinc tailings often contain a variety of toxic heavy metal ions. If entering into the human body through the food chain, it will cause serious damage to plants, animals and people's health. What's more, these heavy metal ions will only be transformed in translation

The extent of the Aznalcllar pyritic sludge spill and its

Mining accentuates and accelerates natural processes. Geochemical reactions in mined areas are more rapid because of the greater accessibility of air through mine workings, wastes and tailings, the greater surface areas for sulfides (especially in tailings) and the different composition of tailings as a result of mineral processing. A considerable amount of literature on pyrite oxidation

Zinc Mining and Processing: Everything you Need to Know

Zinc ores are obtained by many mining techniques, ranging from open-pit mining to the normal underground methods. The most common underground method of ore extraction is cut-and-fill stopping, in which tunnels are dug to moderate depths, branching away from the mine holes. The small fraction of zinc sulfide minerals present in the ore provides necessary benefits in order to produce a

Removal of metals from lead

Lead-zinc tailings used for this study were collected from a lead-zinc mine plant in Shaoguan, China. Lead-zinc mine tailings were prepared by crushing and screening the material to particle sizes below 74 μm. A representative sample of the mine tailings was pulverized to conduct the chemical and mineralogical analysis. The pH of the tailing was determined using a solution of tailings and
