Manual separation process of volcanic sand and rocks without excavator

WELCOME TO MY CHANNEL... All the material in this video is original and I recorded it myself on the spot.
This channel contains black sand extraction activities manually without the help of heavy equipment (excavators), so that the natural preservation is maintained and sustainable.
The black sand here comes from volcanic sand or sand from volcanic eruptions, and we all know that volcanic black sand is the best material for building materials, making buildings very strong, strong and good.
