Embodiment 1

[0029] Preparation of Environmental Mineral Concentrates

[0030] 1) Sieve the andesite after crushing and drying, pour 5.5 parts by weight of the sieved andesite powder into 7 parts by weight of dilute sulfuric acid with a concentration of 20%, stir well and let stand for 24 hours.

[0031] 2) Add 3.5 parts by weight of citric acid to the mixture obtained in step 1), stir well and let stand for 24 hours.

[0032] 3) 15 parts by weight of liquid obtained after filtering the mixture obtained in step 2) is mineral concentrate. Add 85 parts by weight of distilled water to the mineral concentrate, mix it evenly and put it into an acid-proof container for dark preservation.

Embodiment 2

[0034] Environmental mineral concentrate is used to make super humus to inhibit the dissolution of heavy metals in soil

[0035] (1) Cow dung and straw are mixed in a ratio of 1:1 by weight, and the mineral concentrate that yeast and example 1 are made is added thereto, and every 1 cubic meter of mixed material adds 200g yeast and 30ml mineral concentrate , the concentrated mineral solution needs to be diluted with water and then added to the mixture, the water content of the mixture is adjusted to 60-65%, and fully stirred and mixed.

[0036](2) Pile at least 10 cubic meters of mixed material sprayed with mineral liquid into a heap with a height of 1.5 m and a width of 2.5 m, and carry out aerobic fermentation and decomposition. After three fermentations, about three months. The first fermentation takes one month, and the temperature will exceed 70°C on the third day after the pile is completed. Therefore, the pile needs to be turned for the first time on the fifth day. Afte...

Embodiment 3

[0041] Test of Mineral Concentrate Used in Domestic Sludge Removal of Heavy Metals

[0042] (1) Mix the sludge and rice straw at a volume ratio of 1:3. The content of lead and its compounds in the sludge is 0.11 mg / L, and the content of arsenic and its compounds is 0.015 mg / L. Add 200g yeast and the mineral concentrated solution of 30ml embodiment 1 in the mixed material of cubic meter, this mineral concentrated solution needs to add after diluting with water, the water content of mixed material is adjusted to 60%, carry out sufficient stirring and mixing.

[0043] (2) At least 10 cubic meters (maintaining temperature) of the mixture sprayed with mineral liquid are piled up into a pile with a height of 1.5m and a width of 2.5m for aerobic fermentation and decomposition. After three fermentations, about three months. The first fermentation takes one month, and the temperature will exceed 70°C on the third day after the pile is completed. Therefore, the first turning over is re...

Abstract

Provided are an extraction method of mineral concentrate for environmental restoration and application thereof. The extraction method comprises the following steps: 1) drying and screening andesite after the andesite is smashed, pouring screened andesite powder of 5.5-7 parts by weight into 7-14 parts by weight of dilute sulphuric acid with the concentration to be 10-20wt%, and standing for 24h after mixing evenly; 2) adding citric acid of 3.5-5 parts by weight into a mixture obtained in the step 1), and standing for 24h after mixing evenly; 3) filtering the mixture obtained in the step 2), and obtaining filtrate which is the mineral concentrate; and 4) supplementing distilled water into the mineral concentrate, and then pouring the mineral concentrate into an acid-resistant container after mixing evenly so as to perform storage in darkness. The mineral concentrate obtained by the method can be used for composting, manufacture of humus, sewage purification, agriculture and gardens, elimination of unhealthy odor, killing of harmful bacteria and the like, various polluted environments are effectively restored, the purification function of environmental mineral is achieved, and the mineral concentrate is stable and reliable.

Description

technical field [0001] The invention relates to an extraction method and application of a mineral concentrate for environmental restoration, and belongs to the technical field of environmental mineral material manufacturing. Background technique [0002] In the 1980s, environmental geochemistry was born in the study of water-rock interaction, surface mineralogy and the earth's environment, while environmental mineralogy was a new discipline that appeared in the 1990s. At present, international environmental mineralogy academic exchanges are becoming more and more frequent, and environmental mineralogy has become a very prominent and important topic in the international mineralogy community. [0003] Environmental mineral materials refer to a class of mineral materials composed of minerals and their modified products that have good coordination with the ecological environment or directly have the functions of preventing pollution and restoring the environment. The purificati...
