They may be toxic or present other hazards.
Bulking of sand means increase in it's volume due to presence of surface moisture . The volume increases with increase in moisture content . The volume may increase up to 20 to 40% when moisture content is 5 to 10 %.Due to moisture in each particle of sand, sand gets a coating of water due to surface tension which keeps the particles apart. This causes an increment in volume of sand known as Bulking.- Edited by KASEE SREENIVAS# Hindustan Construction Company
Roof ventilation is necessary so that the air is in constant circulation keeping moisture levels low causing less future damage. Roof ventilation also increases energy efficiency in warmer climates.

Tailings Processing is our operations division which provides a chemical free, environmentally friendly solution to the process of extracting minerals from tailings. Their technique also reduces the negative environmental effect of the chemicals remaining in the tailings from the original mining process.
In mining, tailings are the unwanted byproduct that affects the environment. But with the separation process called GravSep, acid forming mineral content of the tailings is reduced. The result: cleaner tailings. Mining usually produces byproducts, called tailings, that are harmful to the environment. But with the physical separation process, which is GravSep, harmful substances in the tailings are significantly reduced.

Water itself is not moist, as moisture refers to the presence of moisture or water vapor in the air. However, water can contribute to moisture when it evaporates and increases humidity in the air.
Relative humidity increases.
Tailings
Tailings are the dirt left after sifting out the gold, so they look like piles of dirt.
The waste material left after a mineral has been extracted is called tailings. Tailings are the byproduct of the mining process, and they often contain leftover minerals, water, and other materials that were not extracted during mining. Proper disposal and management of tailings are crucial to minimize environmental impacts.
