Process Water Management and Seepage Control in Tailings Storage Facilities: Engineered Environmental Solutions Applied in Chile and Peru
Round 1
Reviewer 1 Report
There is a possibility that, by applying thermal treatment, the membrane may change its properties so that it no longer provides long-term resistance to the physical and chemical factors to which it will be exposed. In this case, at the joints, the risk to appear infiltrations is somewhat high. A prior experimental study regarding the lifetime of the welded areas vs the membrane would have been advantageous.

Reviewer 2 Report
This is a well-written article, comprehensive and good to read & understand.
May be accepted in its present form with only minor English/grammar corrections. My single comment to the author is as follows -
Section 1.2 (page NO 4) describes the 'aim of the article, though well written, as a reviewer, I feel to shrink this section into a single paragraph (05 -06 lines) and make it crisp. This will enhance the readability of the article and remove redundancy. Many words are already covered in different parts of the manuscript and very well described, so no need to repeat them. The reader will understand on their own.

Reviewer 3 Report
This article describes the use of geosynthetics liners and cutoff trench – plastic concrete slurry walls -grout curtain systems in TSF dams in Chile and Peru mining, with the objective to decrease seepages to environment, considering different dam material cases such as: cycloned tailings sand dams, borrow dams, and mine waste rock dams. Finally, this article discusses aspects of geosynthetic technology acceptance in the local regulatory frameworks, lessons learned, and advances.
This is a engineering application type of article. This article is well written and can be accepted after solve the following two problems:
(1)The introduction is rich, but what is the main innovation of this article?
(2) The discussion part is too simple. Could you please further discuss the use of geosynthetics in TSF dams.
