Hello. The images and sounds are very interesting in your videos. What are these sands used for?
Thank you very much, this sand is used to build houses made from sand and stone as well as a mixture of asphalt and concrete
@@DeniMerapi Thank you very much for your answer.
Aren't these volcanic sands that are full of minerals?
I thought they use black sand to extract minerals like iron.
