A Brief Introduction to the Types of Surface

Dredging is a method of obtaining mineral deposits from the bottom of rivers oceans harbors and streams As compared to other mining methods where the ore has to be accessed by removing material above it in this case the river makes the job easier by directly transporting minerals from upstream areas Dredging involves scooping up mud from the bottom of the water body removing the
