湿法炼铜的盈利核心来自于低品位矿石的折价，毛利率水平较高 火法炼铜核心盈利模式为赚取铜精矿加工费，盈利空间狭窄且周期性波动剧烈，相比之下湿法炼铜创造 的价格差盈利空间更大。湿法炼铜的原材料可为低品位氧化矿、原生矿等，可使湿法冶炼厂在扩大原材 料选取范围、保障原材料供应充足的同时，在采购时获得较高的折扣计价系数，即更低的原材料价格。 这种"低进高出"的价格差，构成了湿法炼铜高毛利的核心，其毛利率的韧性往往强于火法炼铜。当铜精 矿供应紧张导致TC/RC下跌时，湿法冶炼厂仍可以收获一定的盈利空间。 湿法铜冶炼企业毛利率在30%左右，显著高于火法炼铜毛利率 氧化铜矿主要分布在刚果(金)、赞比亚、智利等地区，因此湿法炼铜也广泛分布在以上地区，但是中资 企业主要投资于刚果(金)、赞比亚地区，其中又可以分为两大类，一类是以自有铜矿为主配套冶炼设 施，例如紫金矿业、洛阳钼业等企业，另一类是以湿法冶炼厂为主的企业，例如盛屯矿业、腾远钴业 等，鉴于盈利模式的差异性是由于冶炼厂带来的，该行主要梳理第二类企业，其铜业务毛利率普遍在 30%左右，与火法冶炼厂10%以内毛利水平形成鲜明的对比，也从数据上证实了不能把湿法炼铜企业简 单看作 ...

1. Report Industry Investment Ratings No relevant content provided. 2. Core Views of the Reports Industrial Silicon - The price of industrial silicon is expected to remain in a low - level oscillation. In November, the supply and demand of the industrial silicon market will both decline, with a larger decline in supply. However, due to the large supply base and the replenishment of the spot market by cancelled warehouse receipts, there is still expected to be inventory accumulation pressure. The main price fluctuation range is expected to be between 8,500 - 9,500 yuan/ton [1]. Polysilicon - It is expected to maintain a high - level range oscillation. The market is in a situation of both supply and demand decline, with inventory accumulation expected in each link, but strong spot support. The backwardation market structure will remain. For trading strategies, try to go long at around 50,000 for futures; hold or take profit on sell put options for options, and consider buying straddles if volatility decreases [2]. Tin - With strong fundamentals, a bullish view on tin prices is maintained. Hold previous long positions and pay attention to macro - end changes and the recovery of supply in Myanmar [4]. Aluminum - Alumina is expected to maintain a bottom - level oscillation, with the main contract operating in the range of 2,700 - 2,850 yuan/ton. Whether the market can rebound depends on the actual production cut scale of existing enterprises and the inventory inflection point. Electrolytic aluminum is expected to maintain a high - level oscillation, with the Shanghai aluminum main contract operating in the range of 21,100 - 21,700 yuan/ton. Focus on overseas monetary policy trends and domestic inventory destocking rhythm [6]. Zinc - Zinc prices are expected to oscillate. The supply - side pressure has gradually eased, and the demand side has shown a structural improvement. However, the terminal demand has remained stable, and there is limited upward momentum. The main reference range is 22,200 - 22,800 yuan/ton [7]. Copper - In the medium - to - long - term, the supply - demand contradiction supports the upward movement of the bottom center of copper prices. Pay attention to macro - drivers such as overseas interest - rate cut expectations. The main reference range is 85,500 - 87,500 yuan/ton [8]. Nickel - The macro - situation is temporarily stable, and the fundamentals remain weak. However, due to upstream production cuts and low valuations, the market may oscillate and repair. In the medium term, the abundant supply will still restrict the upward space of prices. The main reference range is 116,000 - 120,000 yuan/ton [9]. Aluminum Alloy - The price of ADC12 is expected to maintain an oscillating pattern in the short term, with the main contract operating in the range of 20,300 - 20,900 yuan/ton. Pay attention to the improvement of scrap aluminum supply and the change in downstream procurement rhythm [11]. Stainless Steel - The policy - driven effect is difficult to be directly transmitted in the short term, cost support is weakening, and the fundamental structure has not improved significantly. There is still pressure on the supply - side steel mill production schedule and social inventory, and the demand is weak in the off - season. It is expected to oscillate, with the main operating range of 12,300 - 12,700 yuan/ton [13]. Lithium Carbonate - The market is expected to oscillate and adjust in the short term, with the main reference range of 90,000 - 95,000 yuan. Although the market has a bullish sentiment, there is limited substantial new driving force [15]. 3.
