Sand and Gravel Mining - Encyclopedia of Arkansas

Methods of mining sand and gravel depend upon the size and type of deposit but most often consist of open cuts. Sand and gravel deposits not only contain variable percentages of sand- and gravel-sized materials but often contain considerable clay. Depending on the desired properties of the material, clay content may be either a plus or a minus ...
