Study on the precipitation of iron and the synchronous removal mechanisms of antimony and arsenic in the AMD under the induction of carbonate rocks

However, the AMD secondary iron flocs containing a substantial number of iron oxides or hydroxide can be precipitated in AMD, and can be neutralized by carbonate rocks. We quantitatively examined the chemical stability of AMD neutralizing products containing Sb and As, as well as the release of iron, Sb, and As well as the phase change of minerals at different pH levels as stability indexes. This research may help clarify the secondary mineral's formation during the treatment of AMD by carbonate rocks as well as the identification of metals from AMD secondary products containing Sb and As, which sheds light on and provides theoretical basis for passive treatment of AMD that contains these two components in the future.

Study of Adsorbed Organic Layers in the Pore Space of Carbonate Rocks

The results of morphological investigations of samples of carbonate rocks of an oil field are presented, making it possible to identify and analyze organic adsorbed layers on the surface of mineral particles that have arisen due to the adsorption of the polar components of matrix oil.

Exploring the Risk Thresholds of Soil Heavy Metals in Carbonate and Non-carbonate Rock Areas: The Case of Qianjiang District in Chongqing, China

To determine whether the national soil heavy metal standards are applicable to some carbonate and non-carbonate soil samples in Southwest China, rice and rhizosphere soil samples were collected in Chongqing and tested for heavy metals, pH, and other chemical properties.

Study of the karst development rate of the Jinping porous carbonate rock formation based on porosity analysis of rock images

By combining the historic karst growth rate with the porosity magnification, we achieved the new karst growth rate. The two sets of results were considered to be consistent by the 0̆0b15 -u00b1 5 % standard. To test the image analysis's reliability, we used the common carbonate rock research technique to perform a laboratory simulation experiment on carbonate rocks. The karst formation rate of the carbonate rock formations in the Jinping area has increased.
