  A new and distinctive Rhaphiolepis indica plant, characterized by its compact, mounding form, unique branching structure, and white flowers flushed with pink at first opening. Plants grow wider than tall, are drought tolerant, and do not require pruning. Cold tolerance has been observed to USDA Zone 7B. In container culture, plants are observed to have a superior shelf-life. The new plant is a Rhaphiolepis , typically useful as a landscape plant.

  New and improved collector compositions for use in froth flotation processes for the beneficiation of mineral values from base metal sulfide ores are disclosed. The collector compositions comprise at least one hydrocarboxycarbonyl thiourea compound selected from compounds of the formula: ##STR1## wherein R.sup.1 is hydrogen or R.sup.2 ; R.sup.2 is selected from saturated and unsaturated hydrocarbyl radicals, hydrocarboxy radicals and aromatic radicals; and R.sup.3 is selected from saturated and unsaturated hydrocarbyl radicals, alkyl polyether radicals and aromatic radicals, said R.sup.2 and R.sup.3 radicals, optionally, and independently, being substituted by polar groups selected from halogen, nitrile and nitro groups. The use of the hydrocarboxycarbonyl thiourea collectors provides excellent metallurgical recoveries of sulfide mineral values in froth flotation processes conducted over a very broad range of pH including acid, neutral and mildly alkaline pH.

  A process for the beneficiation of copper sulfide mineral values from base metal sulfide ores with selective rejection of pyrite and/or pyrrhotite or other gangue minerals at pH values of below about 10.0 by froth flotation is disclosed. The process includes the use of a new and improved collector which at pH values below 10.0 exhibits unexpectedly high collector activity for copper sulfide minerals and selectively rejects pyrite and other gangue sulfides or non-sulfides. The collector for copper mineral values for use in the process comprises at least one hydrocarboxycarbonyl thiourea compound having the formula: ##STR1## wherein R.sup.1 is hydrogen or R.sup.2 ; R.sup.2 is C.sub.1 -C.sub.8 alkyl and R.sup.3 is C.sub.1 -C.sub.6 alkyl or phenyl. In a preferred embodiment of the present invention, froth flotation is conducted under acid pH conditions by adjusting the pH of the flotation slurry with sulfuric acid. The process provides excellent metallurgical recoveries of copper sulfide mineral values of high grade at a substantial reduction in lime consumption and reagents costs associated with prior art flotation separation methods.

  本发明公开了一种从基础金属硫化矿石中选择性地拒绝黄铁矿和/或辉铁矿或其他岩浆矿物的pH值低于约10.0的铜硫化矿物价值的选矿工艺，通过泡沫浮选。该工艺包括使用一种新的和改进的收集剂，该收集剂在pH值低于10.0的条件下表现出意外高的铜硫化矿物的收集活性，并选择性地拒绝黄铁矿和其他岩浆硫化物或非硫化物。用于该工艺中的铜矿物价值的收集剂包括至少一种具有以下公式的羟基羧酸硫脲化合物：##STR1##其中R.sup.1是氢或R.sup.2; R.sup.2是C.sub.1-C.sub.8烷基，R.sup.3是C.sub.1-C.sub.6烷基或苯基。在本发明的优选实施例中，通过使用硫酸调节浮选浆料的pH值，在酸性pH条件下进行泡沫浮选。该工艺提供了卓越的冶金回收率，以高品位的铜硫化矿物价值为主，并在与先前的浮选分离方法相关的石灰消耗和试剂成本大幅降低。
