Embodiment 1

[0017] The method of photosynthetic bamboo in this example to deal with mining and metallurgy solid waste is as follows: figure 1 As shown, the tailings of ore dressing are piled up into a triangular inner core 1, and the two sides of the triangular inner core 1 are flattened into terraced fields 2, and photosynthetic bamboo 4 is planted on the terraced fields 2. The terraces 2 are fixed by the root system 3 of the photosynthetic bamboo, and the triangular inner core 1 is fixed by the terraces 2, thereby fixing all the solid wastes of mining and metallurgy.

[0018] The harvested photosynthetic bamboo is used to make charcoal, and the obtained biochar is used for metal smelting, which increases the metal recovery rate by 15% to 20% compared with coke, and reduces the cost by 70%.

Embodiment 2

[0020] The photosynthetic bamboo method of the present example is the same as the first embodiment except that the tailings of the ore dressing are piled up into a triangular inner core 1 in the greenhouse.

Embodiment 3

[0022] The photosynthetic bamboo method of this example is the same as the first embodiment, except that the tailings of the ore dressing and the waste rocks of the mining are piled up into a triangular inner core 1 .

Abstract

The invention relates to a method for treating solid mining and metallurgical waste by using photosynthetic bamboo, which belongs to the field of environmental pollution treatment. The method is characterized in that mineral separation tailings or / and mining waste rock or / and metallurgical waste residue are piled to form a triangular inner core (1), two edges of the triangular inner core (1) are flattened to form terraces (2), photosynthetic bamboo (4) are planted in the terraces (2), the terraces (2) are immobilized by roots (3) of the photosynthetic bamboo, the triangular inner core (1) is immobilized by the terraces (2), so all the solid mining and metallurgical waste is immobilized. After harvesting, the photosynthetic bamboo is used for preparation of charcoal, and the prepared biomass charcoal is used for metal smelting. The method provided by the invention overcomes the defect of environmental pollution caused by incomprehensive and incomplete disposal of solid mining and metallurgical waste in the prior art and has the advantages of easiness, practicability, high efficiency, economic performance, low cost and high benefits.

Description

Technical field [0001] The invention relates to the field of environmental pollution control, in particular to a method for treating solid waste from mining and metallurgy with photosynthetic bamboo. Background technique [0002] Existing metal mining and beneficiation always stack the tailings of ore dressing, mining waste rocks and metallurgical waste residues in the open air, without comprehensive and complete disposal of mining and metallurgical solid waste, and let them be stacked in the open air, and the metals in them are exposed to wind, sun, The rain gradually turns into soluble salts to pollute the water body. After the wastewater enters the river, it directly pollutes algae and fish, forming a biological chain pollution. It not only pollutes the environment, but also wastes land resources, and is particularly prone to geological disasters. The ecological disposal of mining and metallurgy solid waste is a difficult problem for our country and the world. Contents ...
