4 | +# **How to Distinguish Metals After Smelting** |
|
5 | + |
|
6 | +After smelting, metals can be distinguished using various methods based on their **physical**, **chemical**, and **mechanical properties**. Below is a detailed explanation of the steps and methods to identify different metals: |
|
7 | + |
|
8 | +--- |
|
9 | + |
|
10 | +## **1. Distinguishing Based on Physical Properties** |
|
11 | + |
|
12 | +### **a) Melting Point** |
|
13 | +Each metal has a unique melting point. By gradually heating and observing the temperature at which the metal melts, you can distinguish them. For example: |
|
14 | +- **Gold (Au)**: Melting point ~1064°C |
|
15 | +- **Silver (Ag)**: Melting point ~961°C |
|
16 | +- **Aluminum (Al)**: Melting point ~660°C |
|
17 | +- **Copper (Cu)**: Melting point ~1085°C |
|
18 | + |
|
19 | +> For mixtures, metals can be separated by gradually heating to specific temperatures and melting one metal at a time. |
|
20 | + |
|
21 | +--- |
|
22 | + |
|
23 | +### **b) Density** |
|
24 | +Density differences are significant among metals. You can measure density to identify metals: |
|
25 | +- **Gold (Au)**: 19.3 g/cm³ (very high density) |
|
26 | +- **Silver (Ag)**: 10.5 g/cm³ |
|
27 | +- **Copper (Cu)**: 8.96 g/cm³ |
|
28 | +- **Aluminum (Al)**: 2.7 g/cm³ (low density) |
|
29 | + |
|
30 | +**Steps**: |
|
31 | +1. Measure the mass using an electronic balance. |
|
32 | +2. Submerge the metal in a graduated cylinder to measure water displacement (volume). |
|
33 | +3. Calculate density using the formula: **Density = Mass / Volume**. |
|
34 | + |
|
35 | +--- |
|
36 | + |
|
37 | +### **c) Hardness** |
|
38 | +The hardness of metals can be tested using the Mohs hardness scale or a scratch test: |
|
39 | +- **Gold (Au)**: Mohs hardness ~2.5 (soft, easily scratched with a fingernail or hard object). |
|
40 | +- **Silver (Ag)**: Mohs hardness ~2.7–3. |
|
41 | +- **Copper (Cu)**: Mohs hardness ~3. |
|
42 | +- **Iron (Fe)**: Mohs hardness ~4–5. |
|
43 | +- **Aluminum (Al)**: Mohs hardness ~2–2.9. |
|

|
52 | + - **Copper (Cu)**: Reacts to produce a blue solution (copper nitrate). |
|
53 | + - **Gold (Au)**: Does not react with nitric acid but dissolves in aqua regia (a mixture of hydrochloric acid and nitric acid in a 3:1 ratio). |
|
54 | + |
|
55 | +2. **Hydrochloric Acid (HCl)**: |
|
56 | + - **Aluminum (Al)**: Produces bubbles (hydrogen gas). |
|
57 | + - **Iron (Fe)**: Reacts slowly, producing hydrogen gas. |
|
58 | + - **Gold (Au), Silver (Ag)**: Do not react with hydrochloric acid alone. |
|
59 | + |
|
60 | +### **b) Sulfide Test** |
|
61 | +- **Silver (Ag)**: Turns black when exposed to sulfur (e.g., hydrogen sulfide gas), forming silver sulfide (Ag₂S). |
|
62 | +- **Copper (Cu)**: Turns green when exposed to sulfides, forming a patina (copper sulfide). |
|
63 | + |
|
64 | +--- |
|
65 | + |
|
66 | +## **3. Distinguishing Based on Appearance** |
|
67 | +- **Gold (Au)**: Yellow, shiny, and resistant to tarnishing. |
|
68 | +- **Silver (Ag)**: White, highly reflective, slightly tarnishes to black when oxidized. |
|
69 | +- **Copper (Cu)**: Reddish-brown, forms green copper oxide over time. |
|
70 | +- **Aluminum (Al)**: Silver-white, retains its color due to a stable oxide layer. |
|
71 | + |
|
72 | +--- |
|
73 | + |
|
74 | +## **4. Using Spectroscopic Analysis** |
|
75 | +Spectroscopic analysis provides the most accurate method to identify metals' composition and purity. |
|
76 | + |
|
77 | +### **Common Equipment**: |

|
84 | + |
|
85 | +3. **ICP-MS (Inductively Coupled Plasma Mass Spectrometry)**: |
|
86 | + - Ultra-high precision for detecting trace elements. |
|
87 | + |
|
88 | +--- |
|
89 | + |
|
90 | +## **5. Magnetic Properties** |
|
91 | +- **Magnetic Metals**: |
|
92 | + - **Iron (Fe)** and **Nickel (Ni)**: Strongly attracted to magnets. |
|
93 | +- **Non-Magnetic Metals**: |
|
94 | + - **Gold (Au), Silver (Ag), Copper (Cu), Aluminum (Al)**: Not attracted to magnets. |
|
95 | + |
|
96 | +--- |
|
97 | + |
|
98 | +## **6. Electrical Conductivity** |
|
99 | +Different metals have distinct electrical conductivities. You can measure conductivity to differentiate metals: |
|
100 | +- **Silver (Ag)**: Highest electrical conductivity. |
|
101 | +- **Copper (Cu)**: Slightly less conductive than silver but still very high. |
|
102 | +- **Gold (Au)**: Lower conductivity than silver and copper but more corrosion-resistant. |
|
103 | +- **Aluminum (Al)**: Lower conductivity than copper and silver but lightweight. |
|
104 | + |
|
105 | +--- |
|
106 | + |
|
107 | +## **7. Industrial Separation Techniques** |
|
108 | +For large-scale mixed metal recovery, industrial equipment can automatically distinguish metals: |
|
109 | +- **Electrostatic Separators**: Separate conductive metals (e.g., gold, silver, copper) from non-conductive materials (e.g., plastics, ceramics). |
|
110 | +- **Gravity Separators**: Separate metals based on density differences. |
|
111 | + |
|
112 | +--- |
|
113 | + |
|
114 | +## **8. Layer Separation After Melting** |
|
115 | +When melting metal mixtures, metals with different densities form layers: |
|
116 | +- **Gold (Au)**: Sinks to the bottom due to its high density (19.3 g/cm³). |
|
117 | +- **Silver (Ag)**: Settles above gold. |
|
118 | +- **Copper (Cu)** and **Aluminum (Al)**: Form layers higher up due to lower densities. |
|
119 | + |
|
120 | +--- |
|
121 | + |
|
122 | +## **Summary** |
|
123 | +- **Simple Methods**: Color, magnetic properties, density, and hardness. |
|
124 | +- **Accurate Methods**: Spectroscopic analysis, chemical reactions, and conductivity testing. |
|
125 | +- **Industrial Methods**: Electrostatic and gravity separators, or layer separation during melting. |

11 | +大多数策略师预测**S&P 500**将迎来一个平均年份(他们每年都这么做)。一些预测稍低于平均水平,但不会太多(**德意志银行**最近的调查预测,该指数平均上涨5.2%,略高于长期实际回报率略低于5%的水平)。 |
|
13 | 12 | |
14 | -尽管**Central Bank**介入后货币有所反弹,货币抛售已经蔓延至其他资产。五年期信用违约掉期的利差宽度超过任何发展中国家的同行,本地政府债券的收益率飙升至自前**President Dilma Rousseff**被罢免以来的最高水平。 |
|
13 | +但有一件事值得注意。一年之中市场提供平均回报的情况相当罕见。市场偏爱极端。正如**BCA Research**的分析师指出的那样,“只有大约四成的年份,回报率在所有卖方公司为明年预测的范围内。如果排除异常值(即前两和后两预测),这个数字下降到17%。换句话说,几乎所有主要卖方公司都聚集在一个在不到五分之一年份中出现过的范围。” |
|
15 | 14 | |
16 | -由于**Central Bank**被迫提高利率以试图控制对通胀预期的损害,股市暴跌抹去了超过2900亿美元的市值,导致**Ibovespa**在美元计价方面落后于所有主要股票指数,仅比**Latvia**和**Mexico**的指数落后。 |
|
15 | +大胆预测**S&P 500**可能跌破5,500(如**BCA**所做)或上涨超过7,100,而不仅仅是上涨5-10%左右,可能看起来很冒险。但正如**BCA**所说,“一个已发生60%的结果可能比一个已发生40%的结果更有可能!” |

20 | -**Gramercy Ltd.**伦敦分公司的首席策略师**Simon Quijano-Evans**表示:“价格走势告诉我们,巴西的领导层可能需要尽快应对市场对财政的担忧。” |
|
19 | +好时光很少会永远持续下去。但坏时光也不会永远持续。最终,市场会回归均值。被低估的股票会上涨,热股会下跌。**Oaktree Capital**的**Howard Marks**在2012年的一篇报告中对此有深入讨论(请聆听我们与他的采访)。 |
|
21 | 20 | |
22 | -**Lula**正在运营一个已扩大到约占巴西国内生产总值10%的预算赤字。他的经济团队上个月公布了一系列财政措施,同时还增加了税收豁免 —— 这让市场对政府控制公共支出的意愿产生了怀疑。 |
|
21 | +“投资者忽视过去的趋势是非常有趣的,”**Marks**说。不过,无论你多么喜欢认为这不会发生,“肯定还会有另一个周期,另一个泡沫,另一个危机。总会有另一个时期,人们因为未来看似无限而为激动人心的想法支付过高价格,然后经历一个幻灭和价格崩溃的时期。总会有一个时期,杠杆被过度使用,随后这会导致人们遭受重大损失。” |

|
23 | +这一点值得记住,同时考虑到大多数市场在平均估值附近波动,且更多的**美国家庭**期望股市继续上涨,这与**互联网泡沫**高峰期相比,美国股票的估值处于历史最高水平。内部人士一直在抛售。**AI**还有大量工作要做,才能帮助**美国**继续增长以匹配其估值。 |
|
25 | 24 | |
26 | -膨胀的赤字 —— 一个从**France**到**Colombia**都引发投资者焦虑的话题 —— 也是新兴市场面临的困难时期。发展中国家在迈向2025年时,还要应对**China**的经济困境、持续的地缘政治紧张局势以及**US President elect Donald Trump**政策对美元和全球利率路径的不确定性。 |

28 | -虽然**Central Bank**的干预可能为**雷亚尔**提供一些暂时的缓解,但在货币贬值至新的历史低点后,分析师们仍在努力寻找其支撑点。本地财富管理公司**Oriz Partners**认为其升值空间“很小”,而**Wells Fargo**则表示,到2026年第一季度,汇率可能达到7雷亚尔兑1美元 —— 比目前水平下跌13%。 |
|
27 | +到2025年,这可能会给落后的**英国**市场的投资者一些坚持的理由。**Peel Hunt**的分析师表示,有“强大的未来增长和现金流指标”可能最终让市场再次走高。上周中旬,**英国**市场正处于其有记录以来最糟糕的四分之一世纪边缘(有1692年的数据),运行速度甚至与1900-1924年期间的+2.3%每年相当。那是一个包括世界大战、疫情和GDP下降20%的迷你萧条的时期(见下方的**德意志银行**图表)。 |

32 | -**Standard Chartered Bank**的经济学家**Dan Pan**表示:“巴西的高利率和相对低廉的估值可能会提供一些支撑,但如果市场对财政可持续性的信心不足,很难扭转这一趋势。” |
|
31 | +有一种观点(主要基于**Jeremy Siegel**1994年的著作《长期投资的股票》)认为,只要坚持持有股票,就不会亏损。然而,这并不像你的财务顾问可能让你认为的那样真实。正如**Edward McQuarrie**教授指出的,假设如果你持有股票20年或更长时间,它们实际上变成了“具有高于市场利率的存款凭证”是一个危险的假设。股票确实可以带来巨大的回报,且那些有幸在过去一个世纪投资于**美国股市**的人确实获得了这些回报。但这并没有保证。 |
|
32 | + |
|
33 | +相反,**McQuarrie**写道,有许多案例显示,即使排除战争撕裂的国家,其他地方的投资者在持有股票20年或更长时间后也会亏钱。他的历史图表显示了**意大利**、**奥地利**、**法国**、**日本**等国家最终处于亏损状态。“当你投资股票时,你是在下注,”他说。“即使你投资于**S&P 500**这样的广泛多样化指数,这仍然是一种赌注。即使你持有20年,这仍然是一种赌注。” |

|
35 | +### 如果股票不上涨,被动投资不再胜出 |
|
36 | + |
|
37 | +**美国**不在**McQuarrie**的20年亏损名单上。但如果市场长期内不如预期上涨的风险比之前更高,被动投资是否仍然有意义?最近支持被动投资的一个较好论点基于**Hendrik Bessembinder**的研究,他说大多数个股对投资者来说都是亏钱的。自1926年以来,仅有4%的个股创造了**美国股市**财富。全球范围内,1%的个股创造了90%的股权财富。根据**BCA**的分析师,这应作为“多样化益处的震撼性提醒”。如果错过了少数上市赢家,你的投资组合将遭受超额表现不佳。 |
|
38 | + |
|
39 | +另一种看待**Bessembinder**的研究的方法是与**McQuarrie**的研究相结合。如果市场在实际方面在20年内可能不会上涨——这在估值非常高时往往会发生(这不是预测,仅供参考)——多样化不会有太大帮助。相反,你需要像**Baillie Gifford**那样看待它。对于这家总部位于**爱丁堡**的基金经理来说,**Bessembinder**的工作提醒人们,如果投资是关于大赢家,那么它也应“几乎完全专注于识别、拥有和支持这些最终推动长期回报的卓越企业。” |
|
40 | + |
|
41 | +但这并不总是有效(尽管在过去十年中上涨了320%,**Baillie Gifford**的旗舰投资信托**Scottish Mortgage**仍比三年前的高点低30%)。然而,被动投资总是优于主动投资的观点并不完全正确。高信念、高主动份额的投资在你想象中的表现要好得多——如果**BCA**的预测比平均分析师的预测更准确,它可能会有一个比你预期更好的十年。 |

|
45 | +**股东民主的兴起**:在**英国**,**LGT Wealth Management**刚刚推出了一种传递投票系统,提供投资者对其投资的上市公司股票进行投票的能力。许多**美国**公司已经提供了这一选项,但这对**英国**的股东资本主义是向前迈出的一大步。 |
|
46 | + |
|
47 | +**合法内部交易的兴起**:**英国金融行为监管局(FCA)**正在就“用于交易私人公司股票的新型股市”进行磋商。这可能是件好事——流动性、透明度等等。但它也带来了一种奇特现象:**FCA**表示,这个市场将“没有内部交易机制”。一些投资者将比其他人拥有更多信息,他们“不会被禁止基于这些信息进行交易”。**彭博社**的**Matt Levine**对此有一些看法。还有一份来自**英格兰银行**的最新研究提醒人们,私募股权支持的公司比其上市同类更容易破产。换句话说,你不想从比你有更多信息的人那里购买。 |
