In the joint meeting of the National Center for Strategic Studies of Agriculture and Water and the Mines and Mineral Industries Commission of the Iran Chamber, a report on "Estimating the water needs of mines and related mineral industries in the horizons of 1415 and 1425" prepared by Pouya Strategic Research Institute , presented.

According to the Iran International Stone Exhibition, in the joint meeting of the National Center for Strategic Studies in Agriculture and Water, the Mining and Mineral Industries Commission of the Iran Chamber, a report on "Estimating the water needs of mines and related mineral industries in the horizons of 1415 and 1425" Research - Dynamic knowledge strategy engineering has been prepared, presented.

In this meeting, the key actions and achievements of this study were discussed in several topics. The results obtained from the specific statistics of this study of selected mines in the country, evaluation of existing data in the country, analysis of upstream documents and related global experiences and finally the development scenario framework in planning horizons and the results of estimating water demand and water supply were the most important axes. . This study was conducted at the National Center for Strategic Studies in Agriculture and Water in cooperation with the Mines and Mineral Industries Commission of the Iran Chamber of Commerce and Industry, and the Macro Planning Office of the Ministry of Energy supervised the study.

First, the survey process and the characteristics of the questionnaire and receiving information from selected mines and the criteria for selecting selected mines and the process of modifying and finalizing the results obtained from the survey were described. The results show statistical conflicts and indicate major differences in the census results of 1393 and 1396 of the Statistics Center of Iran. Meanwhile, according to the explanations of Dr. Davood Reza Arab, the moderator of this report, the changes considered in the report are not linear and the futuristic approach is the basis for its preparation, and the changes and changes in the field of mines have been considered together.

Major differences in the information of the Statistics Center of Iran and the database of the Mining Engineering System in the provinces, comparison of mining information of the Ministry of Industry, Mines and Trade with the Statistics Center of Iran and the Mining Engineering System, major differences in the annual trend of mining information of the Statistics Center of Iran. And the results obtained from studies with the national census of the Ministry of Energy are also mentioned as other statistical conflicts in this report.

By analyzing the water consumption of mines in the whole country based on the information of the Statistics Center of Iran and corrective water consumption in 1393, it was found that 52.7% of the total water consumption of mines belongs to Kerman province and 17.8% to Yazd province and about 20% (respectively It is consumed in 8 provinces of Khorasan Razavi, East Azerbaijan, Tehran, Isfahan, Fars, Markazi, Khuzestan and Sistan and Baluchestan and the remaining 10% of mineral water consumption is consumed in 21 other provinces.

Analysis of global experiences of mines and mining industries

"Analysis of Iran's position, future market developments, water consumption efficiency and use of technology" was another part of this report, in which Iran and world mining production, mineral consumption and mineral consumption, Iran and world mining economy, materials trade Minerals and Mineral Industries in Iran and the World, Water Consumption Productivity and Improved Energy Efficiency Separately Explain and Reduce Wet Zone / Open Zone in Waste Storage Facilities, Reduce Fine Granule Production During Grinding to Keep Waste Water Down, Improve Waste Condenser Performance, Reduce Water losses through condensation or disposal of pulp wastes, reduction of water losses through installation of drainage in TSF, reduction of water losses through tailings density, reduction of water losses through tailings classification, etc. were proposed with the aim of reducing mine water consumption.

In addition, collection and reuse of surface runoff, reuse of mine irrigation system water, reuse of cooling water, reuse of dust separator water, reuse of gray water and reuse of off-site wastewater And water resources are an alternative to solutions that, according to global experience, can be effective in the field of mineral water reuse.

Surface water recycling facility (TSF) recycling, leakage recycling from tailings storage facility (TSF), waste condensate overflow recycling, concentrate or intermediate condensate overflow recycling and mine wastewater recycling were also mentioned as solutions for wastewater treatment.

Components of water demand estimation of industry

 In the report "Estimation of water needs of mines and related mining industry chains in horizons 1415 and 1425", with emphasis on water consumption in horizon 1400, four components of determining the water consumption of each industrial activity in planning horizons, determining the types of industrial activity and its share Planning, determining the volume of each industrial activity in the planning horizons and determining the share of each province in the total activities in the planning horizon to create regional balance as the most important components of estimating the water demand of industry is emphasized and emphasized. Industrial activity groups in each province and city to be calculated and estimated. Therefore, the final results in 9 groups of mining activities and mining industries in 429 cities in horizons 104, 1415 and 1425 have been estimated in different scenarios. The final scenario has been done in two stages and in the first stage the balanced and balanced development of all regions and in the second stage the use of regional reserve capacities and the characteristics of establishing industries near the mines as well as the capacities of increasing share of global markets. Foresight and growth forecasts have been used to create growth, and the creation of balanced development has been determined by the two main indicators of income balance and forward-looking employment balance. The changes in the economic structure, and especially the changes in the mineral structure and the industrial structure in the regions have been forward-looking and in order to achieve the main goals and orientations.

Mineral water supply framework and related mining industry chain

In the mentioned report, also with the aim of how to supply water to the mines and the chain of related mining industries, it is proposed to identify the water consumption categories of the units in the first step and then the categories of regions based on access to water resources. In these two stages, the type of activity, the volume of water consumption per unit, water use efficiency per unit, programmable water, allocable water, future development plans, the status of plains and emergencies are the most important issues to be identified and after these two stages, the matrix Water supply of mineral units and related mineral industries chain from available water sources, paying attention to the requirements and criteria of water supply of mineral units and related mineral industries chain should be on the agenda.

After presenting this report, Bahram Shakoori, Chairman of the Mines and Mining Industries Commission of the Iran Chamber, and Abbas Keshavarz, Research Deputy of the National Center for Strategic Studies in Agriculture and Water, expressed their views.

According to Bahram Shakoori, accurate estimation of the results of this research depends on the development and implementation of a detailed questionnaire as well as how to extract the data. He also called for attention to be paid to the two components of security and demand in examining the results of this report. He stressed that the accuracy of the questionnaires should be evaluated and verified, and it should be determined to what extent the change in water consumption technology in the mining sector has been considered.

The head of the Iran Chamber of Mines and Mineral Industries Commission emphasized: "Another component that should be considered in this report is the new innovations that have been included in the water needs of the mines and mineral industries of the provinces in the horizons of 1415 and 1425."

However, he believes that this report, if operational, could cover many of the shortcomings in the mining sector.

Referring to the fact that the share of water consumption in the mining and mineral industries is 2%, Shakoori said: "The same amount should be used optimally, and in my opinion, the vacuum of compiling such reports in the field of agriculture, which consume 92% of water resources." They feel strongly.

Keshavarz, research assistant of the Center for Strategic Studies of Agriculture and Water of the Iran Chamber, also called for the implementation of this plan and to prevent duplication of work between related executive bodies, and suggested that the Iran Chamber prepare a letter signed by the chamber's chairman. Samat should also inform other related executive bodies.
