Problems solved by technology

However, when the tailings in the tailings pond are reused, the enterprise generally needs to stop production to dig the tailings or build another tailings pond for turnover, which affects the normal production of the enterprise, increases the burden on the enterprise, and also affects the Enthusiasm for reuse of tailings

Embodiment

[0024] This embodiment is a lead-zinc mining enterprise with a daily processing capacity of 2,000 tons of ore. The repeatable stacking tailings storage capacity built by the technology of the present invention is more than 500,000 cubic meters. The enterprise discharges and excavates alternately in the upstream section and the downstream section according to the production plan. Tailings, tailings are all provided to cement plants as additives.

[0025] figure 1 As shown, about 1,000 meters of the river channel in the "C" bend is intercepted, and the grouted masonry gravity type upstream initial dam 1, dividing dam 2 and downstream accumulation dam 3 are built to form a space for stacking tailings, and the upstream is gradually accumulated in later production. When one section of the accumulation dam 4 and the downstream accumulation dam 5 discharge the tailings, the other section excavates the tailings and sends them to the cement plant, and they are carried out mutually, and...

Abstract

The invention belongs to the technical field of tailing ponds, and particularly relates to a tailing pond capable of achieving repeated stacking. The tailing pond comprises an upstream primary dam arranged at an inlet of a C-shaped or S-shaped bend of a riverway and a downstream primary dam arranged at an outlet of the bend. A division dam is arranged in the middle of the bend. Tailings are stacked between the upstream primary dam and the division dam to form an upstream stacking dam, and tailings are stacked between the division dam and the downstream primary dam to form a downstream stacking dam. A flood discharging tunnel used for draining flood in the riverway is arranged in the position, on the inner side of the bend, of a mountain. An inlet of the flood discharging tunnel is arranged on the upstream part of the upstream primary dam, and an outlet of the flood discharging tunnel is arranged on the downstream part of the downstream primary dam.

Description

technical field [0001] The invention belongs to the technical field of tailings ponds, and in particular relates to a tailings pond that can be stacked repeatedly. Background technique [0002] Mining and dressing enterprises above designated size must build tailings ponds to store tailings from mineral processing operations at the same time as building dressing plants. my country's mineral resources generally have less rich ore and more lean ore. After the mineral processing operation, a large amount of tailings will inevitably be produced. Iron ore with relatively high metal content will produce about 60-80% of the tailings after the mineral processing operation. Some non-ferrous metals or rare metals More tailings are produced after beneficiation operations, even reaching more than 95%. A large amount of tailings are piled up in the tailings pool, which not only takes up a lot of valuable land resources, but also sometimes causes dust and leakage due to poor management of ...
