Häberle et al.  confirmed that the spatial distribution of Twitter content can be studied through various machine-learning techniques, and Gulnerman and Karaman  presented various techniques for mapping social-media data. Text mining has been highlighted as a methodology that can replace existing interview and questionnaire techniques, as it can identify the main content of a given text . Furthermore, this developing technique analyzes the characteristics and location of the main content. The study aims to use maps as an alternative analysis method of identifying the spatial context of environmental conflicts. The present study maps environmental conflicts in South Korea, which has experienced various environmental conflicts due to rapid development in recent years, using spatial text mining and, where possible, online environmental conflict data provided by local governments.Therefore, this study employs a spatial text mining technique to map and organize the content generated by stakeholders in various environmental conflict case studies. Recent advances in these techniques have expanded their applications from comparing the location of McDonald’s outlets to obesity incidence by spatializing Twitter data , to proposing methods for maximizing joy via an emotional analysis of space in a Disney park .
It has been reported that in the presence of dodecyl phosphate (100 ppm) as a collector and sodium silicate (75 ppm) as a depressant at pH 5–6, 80%–98% of dolomite and 12%–28% of magnesite can be recovered (a selective depressant for magnesite in its reverse flotation from dolomite) .206 mg/L), and the results indicate that in this condition the contact angle of dolomite was 19°, where for magnesite it was 89° . Under flotation conditions using anionic fatty acid (Acintol FA-1 tall oil) with varying modifiers—SHMP, tetrasodium pyrophosphate (TSPP), and CMC in neutral to alkalinic region (pH 6–12) float dolomite and sink magnesite—Matis et al.2 in the presence of sodium silicate (12. Moreover, Matis and Gallios  reported that the presence of sodium silicate provided an activating effect on magnesite in the pulp.5 mg/L) at pH 10. These results specified that at various pHs, modifiers such as sodium silicate in carbonate flotation may play different roles (as activator or depressant). Floatability of magnesite and depression of dolomite were examined by anionic sodium oleate (3044. 1988 suggested that selective separation can be further improved in several flotation stages .
Corin and Wiese  speculated that increases in ionic strength might have increased the adsorption of CMC onto floatable gangue and thereby inducing the coagulation of floatable gangue particles.The trend of a decrease in the rate of talc recovery with increasing ionic strength of SPW can be explained by Corin and Wiese  who showed a clear decrease in the rate of floatable gangue recovery with increasing ionic strength. It can therefore be said that the microflotation results of this work are a piece of experimental evidence to that speculation, as the rate of talc recovery decreased as the particles became more passivated, allowing for a more conducive environment for CMC adsorption, and thus impeding their flotation.
