“…Diverse mining companies have their deposits in arid areas, especially in northern Chile, southern Peru, Australia, Africa and Asia [1,2]. In these regions, water availability may be a serious challenge and is the primary purpose for plants to reduce their water demand while avoiding significant alterations in production.…”

“…pH 8), requiring further reagents to deal with the quality of concentrates [5,19]. At a high pH, the seawater divalent cations (Mg 2+ and Ca 2+ ) can hydrolyse to form soluble complexes (e.g., Mg(OH) + and Ca(OH) + ) and varied solid substances (e.g., Mg(OH) 2 , Ca(OH) 2 , etc.). These species may adsorb onto the mineral's surface, which includes the main component of copper tailings such as kaolin and silica.…”

In this study, the viscoelastic properties of quartz and kaolin suspensions in seawater were analysed considering two distinct conditions: pH 8 and 10.7. Creep and oscillatory sweep tests provided the rheological parameters. An Anton Paar MCR 102 rheometer (ANAMIN Group, Santiago, Chile) was used with a vane-in-cup configuration, and the data were processed with RheoCompassTM Light software (ANAMIN Group, Santiago, Chile). The outcomes were associated with the formation of solid species principally composed of magnesium precipitates. The magnesium in solution reduced in the presence of quartz (68 wt %), from 1380 to 1280 mg/L. Since the difference was not large regarding the solid-free seawater, the disposition of solid complexes at pH 10.7 was expected to be similar. The jump in pH caused both yield stress and viscoelastic moduli to drop, suggesting that the solid precipitates diminished the strength of the particle networks that made up the suspension. For the kaolin slurries (37 wt %), the yield stress raised when the pH increased, but unlike quartz, there was significant adsorption of magnesium cations. In fact, the concentration of magnesium in solution fell from 1380 to 658 mg/L. Dynamic oscillatory assays revealed structural changes in both pulps; in particular, the phase angle was greater at pH 8 than at pH 10.7, which indicates that at more alkaline conditions, the suspension exhibits a more solid-like character.

“…Based on these calibrated parameters, the water supply simulation results were validated with the data for 2016 for different water supply types and districts obtained from the 2016 Beijing Water Resources Bulletin. As statistical parameters, the mean relative error (MRE) and coefficient of determination ( R 2 ) were used to examine the quality of the simulation results (Shao et al ):

MRE = \frac{\sum (V_{sim} - V_{real})}{\sum V_{sim}}

R^{2} = {()(, \frac{\sum (V_{sim} - {\bar{V}}_{sim}) (V_{real} - {\bar{V}}_{real})}{\sqrt{\sum {(V_{sim} - {\bar{V}}_{sim})}^{2} \sum {(V_{real} - {\bar{V}}_{real})}^{2}}})}^{2},

where V sim and V real are the simulated and observed value of the variable, respectively, and

{\bar{V}}_{sim}

and

{\bar{V}}_{real}

are the simulated and observed means, respectively.…”

Research Impact Statement: Importance of the MR-SNWDP (middle route of the South-to-North Water Diversion Project) for ensuring available water supplies in Beijing.ABSTRACT: Since its implementation in 2015, the Middle Route of the South-to-North Water Diversion Project (MR-SNWDP) has transferred an average of 45 billion cubic meters of surface water per year from the Yangtze River in southern China to the Yellow River and Hai River Basin in northern China, but how that supply is able to cope with droughts under different scenarios has not been explored. In this study, using the water demand for 2020 as the guaranteed water target, a Water Evaluation and Planning system was used to simulate available water supplies in Beijing under different drought scenarios. In the case of a single-year drought, without the MR-SNWDP, Beijing's water shortage ratio was 16.7%; with the MR-SNWDP, this ratio reduced to 7.3%. In the case of a multi-year drought, without the MR-SNWDP, Beijing's water shortage ratio was 25.3%; with the MR-SNWDP, this ratio reduced to 7.4% and domestic water supply was improved. Our research suggests that to prepare for multi-year drought in the Beijing area, the SNWDP supports increased supplies to the region that would mitigate drought effects. This study is, however, mostly focused on water supply provision to Beijing and does not comprehensively evaluate other potential impacts. Multiple additional avenues could be pursued that include replenishing groundwater, increasing reservoir storage, and water conservation methods. Further research is needed to explore the relative costs and benefits of these approaches.

“…Special attention was paid to the problem of reducing the number of people with access to drinking water [18]. One [19][20][21] of the main subjects in the scenarios of the future was the aggravation of the shortage of fresh water. The World Bank estimates that, a significant change in the situation in the next 50 years could be no expectation: by mid-century of the XXI century already 40% of the world's population will experience increased water stress, 20% -to severely suffer from it.…”
