摘     要
     按照畢業(yè)設(shè)計(jì)任務(wù)書的要求，進(jìn)行了黃沙坪鉛鋅礦優(yōu)先浮選1750噸/日選礦廠設(shè)計(jì)，產(chǎn)品為鉛精礦和鋅精礦。
在湖南郴州的黃沙坪鉛鋅礦進(jìn)行了為期三周畢業(yè)實(shí)習(xí)，收集相關(guān)設(shè)計(jì)資料的基礎(chǔ)上。確定了各車間的工作制度，對(duì)設(shè)計(jì)工藝流程進(jìn)行了選擇和論證，確定了設(shè)計(jì)的工藝流程，即：破碎采用三段半開路流程，磨礦采用一段閉路流程，浮選采用優(yōu)先浮工藝，精礦采用先濃縮后過濾的兩段脫水。
對(duì)設(shè)計(jì)工藝流程進(jìn)行了工藝指標(biāo)計(jì)算，包括破碎、篩分、磨礦、浮選（包括礦漿流程）和脫水流程。對(duì)破碎、篩分、磨礦、分級(jí)、浮選及脫水設(shè)備進(jìn)行了選擇計(jì)算和方案比較，確定了工藝所需的工藝設(shè)備。
進(jìn)行了廠房總體布置，并進(jìn)行了廠房?jī)?nèi)的設(shè)備配置。根據(jù)選廠房的地形條件，沿山坡地布置，其中，粗碎、中細(xì)碎、篩分廠房分開布置，粗碎、中細(xì)碎及篩分車間平行等高線配置。磨礦浮選共廠房配置，其中磨礦采用縱向配置，浮選機(jī)采用橫向配置。濃縮機(jī)配置在露天，過濾機(jī)與精礦倉(cāng)配置在廠房?jī)?nèi)。完成 了粗碎、中細(xì)碎、篩分、磨浮、脫水車間平斷面圖、數(shù)質(zhì)量及礦漿流程圖和設(shè)備聯(lián)系圖共10張。

Abstract
    According to the request of the intruction of plant design for undergraduated, the design of  Huangshaping Pb -Zn Mine concentrator with the capacity of 1750t/d, and the products are lead and zinc concentrate.
On the basis of  practice in Huangshaping Pb -Zn Mine for three weeks, and the collection of data,  The work institutions of each workshop were determined, and the technological process was also chosed and reasoned The process of crushing is three sections with half open circuit, the grinding process is one section with closed circuit, the floation process is selective flotation of lead minerals, and  a process with two sections dewatering circiut which included concentration and filtion was adopted .
Technological parameters of crushing,screening, grinding ,floation(include the circuit of  pulp)and dewatering were computed, respectively. Then the technological parameters of equipments were computed and the schemes of equipments were compared and the optimal equipments were determined.
The general arrangement of concentrator plant and the allocation of equipments in diferent workshop were presented. According to the topography of plant site, plants were arranged along the slope of mountain. The workshops of coarse crushing, middle and fine crushing and screening were aloted independent. Arrangment with parallel contour line of coarse crushing workshop、 middle and fine crushing and screening workshops were used. The workshops of grinding and flotation were put togather, and the longitudinal and lateral plans were used for the mills and flotation machines respectively. The concentrate machines were collocated  seprarted from thefilitering workshop and concentrate bins which were aloted inside. 10 pieces drawing ,such as the workshop of coarse crushing, middle and fine crushing, screening , grinding , floation , dewatering and so on, were finished include a handicraft drawing.

Keywords:  concentrator design, lead and zinc ores, flotation , HuangShaPing
