The importance of the environment is by definition to ensure a better quality of life for the environment around us and future generations, which leads to the important studies that minimize the environmental impact caused by industries that use water in its production process. This study about a foundry cassiterite (tin ore) from the city of Ariquemes Rondônia - RO, and focused on your objective assessment of the quality of wastewater generated from washing of the process gases from the electric furnaces for the reduction of these ore cassiterite. Samples were collected in two stages, the second step reagent added sodium hydroxide to a neutralization and precipitation process and stirring by compressed air. The laboratory responsible for analysis was Bioagro Ambiental parameters with CONAMA 357/05 art. 34. The results showed the first step out of the four parameters example fluoride National Council of Environment (CONAMA) 357/05 710 mg / L, total tin 6.4 mg / L, dissolved iron 34.8 mg / L, pH 2.74 mg / L. It is observed that in the second stage using sodium hydroxide reagent analytical results showed only one parameter out of CONAMA resolution, 810 mg fluoride / L, with a maximum allowed of 10.0 mg / L. Although there was a significant reduction in contaminants is concluded that only the sodium hydroxide does not only treatment process thus requiring. Further study in the treatment of wastewater so that it can be discarded and reused in the production process of the company.

Ethical guidelines for journal publication
The REMOA is committed to ensuring ethics in publication and quality of articles.
Conformance to standards of ethical behavior is therefore expected of all parties involved: Authors, Editors, Reviewers, and the Publisher.
In particular,
Authors: Authors should present an objective discussion of the significance of research work as well as sufficient detail and references to permit others to replicate the experiments. Fraudulent or knowingly inaccurate statements constitute unethical behavior and are unacceptable. Review articles should also be objective, comprehensive, and accurate accounts of the state of the art. The authors should ensure that their work is entirely original works, and if the work and/or words of others have been used, this has been appropriately acknowledged. Plagiarism in all its forms constitutes unethical publishing behavior and is unacceptable. Submitting the same manuscript to more than one journal concurrently constitutes unethical publishing behavior and is unacceptable. Authors should not submit articles describing essentially the same research to more than one journal. The corresponding author should ensure that there is a full consensus of all co-authors in approving the final version of the paper and its submission for publication.
Editors: Editors should evaluate manuscripts exclusively on the basis of their academic merit. An editor must not use unpublished information in the editor's own research without the express written consent of the author. Editors should take reasonable responsive measures when ethical complaints have been presented concerning a submitted manuscript or published paper.
Reviewers: Any manuscripts received for review must be treated as confidential documents. Privileged information or ideas obtained through peer review must be kept confidential and not used for personal advantage. Reviews should be conducted objectively, and observations should be formulated clearly with supporting arguments, so that authors can use them for improving the paper. Any selected referee who feels unqualified to review the research reported in a manuscript or knows that its prompt review will be impossible should notify the editor and excuse himself from the review process. Reviewers should not consider manuscripts in which they have conflicts of interest resulting from competitive, collaborative, or other relationships or connections with any of the authors, companies, or institutions connected to the papers.
